LEICA M : THE BOMBSHELL OF PHOTOKINA 2012

José Manuel Serrano Esparza
SPANISH
Leica has just announced the bombshell of this Photokina Köln 2012: The Leica M, a really masterful unexpected gamble which instantly becomes the flagship of the most important photographic fair in the world of this year 2012.

Leica M with Apo-Elmarit-R 70-180 mm f/2.8 ASPH zoom lens, Visoflex electronic viewfinder and multifunctional M handgrip.

A DREAM COME TRUE
Both the professionals and advanced connoiseurs using Leica M rangefinder digital cameras like the M9, M9-P and M Monochrom, though happy with the great opto-mechanical performance of the new full frame Leica M series cameras which have been created by the legendary German photographic firm since 2009 and the superb assortment of Leica M aspherical lenses, the smallest and lightest ones ever made for full frame 24 x 36 mm digital sensors, and delivering an image quality second to none between ISO 160 and ISO 1250 in colour (M9 and M9-P) and between ISO 160 and ISO 6400 in black and white (Leica Monochrom) have been yearning after having the chance of using their beloved Leica R lenses and zooms connected to a digital full frame sensor able to exploit as much as possible their huge potential, specially with those sporting focal lengths between 100 mm and 800 mm, many of them world benchmarks in their focal lengths and luminosities like the Apo-Macro Elmarit-R 100 mm f/2.8, the Apo-Summicron-R 90 mm f/2 ASPH (incredibly compact), the Apo-Summicron-R 180 mm f/2 ASPH, the Apo-Elmarit-R 180 mm f/2.8 ASPH, the Leica Apo-Telyt-R 280 mm f/4, and even the six top-notch teleobjectives belonging to the amazing Apo-Telyt-R Module System (Apo-Telyt-R 280 mm f/2.8, Apo-Telyt-R 400 mm f/2.8, Apo-Telyt-R 400 mm f/4, Apo-Telyt-R 560 mm f/4, Apo-Telyt-R 560 mm f/5.6, and Apo-Telyt-R 800 mm f/5.6), without forgetting the four elite Leica R zooms: Vario-Elmar-R 21-35 mm f/3.5-4 ASPH (which can be flawlessly used in architectural shots), the Vario-Elmarit-R 35-70 mm f/2.8 ASPH, the Vario-Elmarit-R 28-90 mm f/2.8-4.5 ASPH and the Vario-Elmarit-R 70-180 mm f/2.8 ASPH

Specially during the last four years, the deep research made and the lectures given by James L. Lager, international authority on Leica topics, on the immense possibilities of Leica R Lenses on full frame digital 24 x 36 mm sensors had foreseen what was in the way, along with some really remarkable attempts to connect the amazing Leica R Lenses on superb full frame professional reflex cameras like Nikon D700, Nikon D3, Nikon D4, Canon EOS 5D, 5DII, etc, attaining great results, specially implemented by Leitax firm.


But the great advantage - among many others - of the new Leica M and its just born state-of-the-art 24 megapixel CMOS full frame digital sensor is that it utterly preserves its M camera nature, very compact dimensions and inherent ability to connect the highly comprehensive array of Leica M lenses, and at the same time enables the attachment of all the Leica R lenses in existence through a top-notch quality adapter, it all with a very little and light Leica M body, much smaller than the professional full frame dslrs from Canon, Nikon or Sony, and the great advantages of comfort of use it means, enhanced by the two choices of external viewfinders (the Visoflex electronic viewfinder and the Leica EVF2), which will make possible a very good vision and shooting handheld or with monopods even with the longest Leica R lenses, with a fostered handling easiness provided by the multifunctional handgrip-M. 


Leica M with a newly designed 24 Megapixel Max CMOS image sensor, highly advanced Leica Maestro ipm, Full HD video capability, Live View and full connectivity with the highly comprehensive array of legendary both Leica M and R Lenses. This is undoubtedly the most significant new product of this Photokina Köln 2012.




Leica M with the 11 elements  in 8 groups Vario-Elmarit-R 28-90 mm f/2.8-4.5 ASPH zoom lens, with difference the best professional standard zoom ever made, very compact for its range of focal lengths and focusing by means of the front group. All of the elements are grinded, including the two amazing aspherical surfaces (one of them located in the front element - which required a state-of-the-art exclusive precision grinding and polishing method for it - and the other one in the most back element), the two lens elements of highly refractive glass, and the three elements with anomalous partial dispersion, it all resulting in an impressive second to none image quality across the entire range of focal lengths, even at the widest apertures. Besides, it boasts both the best centering of elements and the most advanced, complex and efficient mechanical scheme (optimizing the lens groups shift) ever implemented in a zoom of its class, which was a conundrum highly successfully solved by Leica, which also managed to build a highly complex mechanical scheme.

The Vario-Elmarit-R 28-90 mm lens presented on December 1 2003, was a highly breakthrough design many years ahead of its time, which anticipated the optical and mechanical quality which would be necessary to match the professional zooms with cameras featuring state-of-the-art full frame image sensors (a very difficult mission to tackle, particularly in borders and corners), an optical and mechanical tour de force in itself, featuring an extraordinary assembly accuracy and the best available optical glasses, turning it into a breed of its own and using the most advanced CNC machines and tool drive contrivances specially developed for this astounding all-around performer, with which Leica managed to build a zoom lens that could be used throughout the telephoto and wide angle ranges connected to the full frame digital cameras that Leica could create (beginning with the hybrid Leica R Modul) in the following decades, 


delivering a resolving power, sharpness and contrast at every focal length of its range between 28 and 90 mm comparable to the best primes at each one of those five most common fixed focal lengths (28 mm, 35 mm, 50 mm, 75 mm and 90 mm). 

It is optically and mechanically better than the excellent Canon EF 24-70 mm f/2.8 L II USM, Nikkor AF-S 24-70 mm f/2.8G ED and the Olympus Zuiko 14-35 mm f/2 ED SWD (equivalent to a 28-70 mm f/2.8 in full frame, because the 4/3 format features much more depth of field), delivering a superior image quality, specially in borders and corners.


On top of the new Leica M camera can be seen the Visoflex EVF, which is inserted in the hotshoe, allowing the use of Leica R lenses.


STATE-OF-THE-ART 24 MEGAPIXEL LEICA MAX CMOS


It is the core of the new Leica M and it is the fruit of a strategic cooperation between Leica Camera AG and CMOSIS, a first-class Belgian firm based in Antwerp and devoted to the creation of very advanced CMOS image sensors, having managed to go beyond the usage of the non linear compression of the signal as a way to tackle the usual limitation of dynamic range by the pixel readout mechanism, developing a new pixel that enables a photodiode readout with a wide dynamic range, which keeps a linear reponse to light.



On the other hand, the global shutter pixel technology implemented by CMOSIS joins together a remarkable shutter efficiency with low read noise by means of a correlated double sampling, as well as being the only global shutter pixel technology compatible with backside illumination devices, it all being fostered by exceedingly fast and accurate column AD converters. 

The new custom-designed sensor chip, featuring 6,000 x 4,000 pixels on a 6 x 6 microns/m2 grid across the active area of 36 x 24 mm2, is manufactured by STMicroelectronics (STM) in Grenoble (France), using 300 mm wafers in their IMG175 CIS technology. 


The imager for the Leica M is based on a 6 x 6 microns/m2 pixel size, delivering a linear full capacity of 40,000 electrons and a linear dynamic range approaching 76dB. 


Pixel data are digitized by patented low-power, high speed 14-bit column AD converters, and the sensor sports an electronic rolling shutter with global reset and noise cancellation through both analog as well as digital correlated double sampling (CDS) resulting in low temporal and spatial noise and non-uniformities.


Special care was taken in the sensor development to reduce crosstalk between neighbouring pixels for a wide range of incident angles. The sensor reduces spatial crosstalk by its very small distance between colur filters and photodiodes. This thin optical stack is optimized for an efficient light coupling into the silicon. Microlenses with a strong curvature and high top height focus the incoming light rays in the center of each pixel´s photodiode, and the resulting low angular sensitivity of the quantum efficiency (QE) at high ray angles was attained by the special features of STM´s 110/90nm CMOS process. It all allows the new Leica M to accept the full assortment of high quality lenses in the camera system, which includes wideangle, large aperture lenses, at their utter optical performance.


Pixel size of 6 x 6 microns/m2 and full frame rate of 5fps are state of the art and comparable to other high end CMOS image sensors used in full frame 24 x 36 mm cameras. 


On the other hand, the full frame 24 megapixel CMOS sensor also allows Leica to offer, for the first time, full HDTV video recording and a Live View preview on a Leica M camera.


And power consumption of the sensor chip at full speed and resolution is specified at 700 mW, being housed in a 78-pin ceramic package covered by a customized glass with antireflective coating and near infrared cut-off filter. 


Most of the technology and internal components of the full frame 24 megapixel Leica Max CMOS sensor is made in France and Germany, and its extremely low power consumption provide great benefits for image quality and battery life alike. 


Though until now the amazing optical and mechanical performance of the Leica M aspherical lenses has anabled the Leica M9 and M9-P to deliver a great image quality with superb DNG archives second to none between ISO 160 and 1250 (something really astounding, because three years are a lot of time in the current digital photographic industry), it was clear that the full blast speed of technology of brands like Sony with its world class digital full frame sensors and Fuji with the great APS-C sensor of its Fuji X-Pro 1 (which in combination with its superb very luminous lenses delivers an image quality more belonging to the full frame scope) were ahead of the 18 megapixel Kodak KAF 18500 CCD of the Leica M9.


It was also clear that the tremendous resolving power and contrast of the Leica M aspherical lenses went clearly far beyond the capabilities of the Kodak KAF-18500, so Leica camera AG has wisely decided to use this new full frame 24 megapixel Leica Max CMOS sensor, which is probably the best 24 x 36 mm digital captor presented in this Photokina Köln 2012 together with the 24 megapixel Sony CMOS Exmor shared by the Sony SLT 99 and the excellent fixed lens compact full frame camera Sony RX1.


Bearing in mind the outstanding results attained during these recent years by the Leica M9 and M9-P with the aforementioned three years old sensor, there can be little doubt to be sure that the symbiosis between the  new Leica M body, the 24 megapixels Max CMOS sensor, the Maestro ipm (technology from the Leica S2) and the superb assortment of Leica M aspherical lenses will deliver a really stratospheric image quality, with staggering dynamic range, impressive high ISO capabilities and the deep color and quality inherent to the cream of full frame sensors. 


Evidently, it seems clear that the best full frame image sensor in the market presently is the 24 megapixel CMOS Exmor and ipm Bionz of the fixed lens Sony RX1 (identical to the one featured by the Sony SLT full frame camera with intercahngeable lenses), boasting a superb dynamic range, grea colour depth, impressive capabilities at high and extremely high ISOS (native ones up to 25,600, and being able to reach 102,400 using the multiframe choice).


Nevertheless, its eems that something really great has been moving in Leica during the last months until finding a suitable formula of full frame 24 x 36 mm sensor able to draw the maximum possible potential of the highly luminous Leica M ASPH lenses, whose quality level goes far beyond all the 24 x 36 mm sensors currently existing.


During the presentation party of the new 26 megapixel Leica M in Köln, Andreas Kaufmann commented that the new 24 megapixel full frame Max CMOS sensor ´is superior to the existing CMOS of other cameras´, which is highly meaningful, since the full frame CMOS sensors of the Sony RX1, Sony LST 99, Nikon D800 and D600 are extraordinary and feature huge capabilities at high and very high isos.


Therefore, it seems apparent that both because of iso limits (6,400) of the new 24 megapixel Leica M and the previous background of Leica in the digital scope, in which Leica has given more importance to other factors decisively leading to the maximum possible of image quality, the new full frame 24 megapixel Leica M won´t have the tremendous capabilities of the aforementioned excellent full frame cameras from Sony and Nikon. 


Then, what could be Andreas Kaufmann be speaking about?


In my viewpoint, there is a high probability that he was referring to the fact that the new full frame 24 megapixel Max CMOS could deliever the best dynamic range generated hitherto by a full frame digital captor.


And it could make sense, because Leica aims are not focused in striving after getting colossal sensitivities between 12.000 ISO and 50.000 ISO and even reaching 100,000 ISO or more, undoubtedly remarkable technological breakthroughs, though it seems clear, as many professional photographers have explained, that with an ISO capability up to 6,400 you have got more then necessary sensitivity to tackle shooting handheld vast majority of photographic contexts or assignments.


The users of Leica M cameras and lenses do know very well the tremendous suitability of this photographic system for hand and wrist shooting without any trepidation, which is its natural biotope where it works better, taking advantage of the very small camera size for its format, the lack of mirror and the great luminosity, very light weight and exceedingly small size of its lenses, so a full frame sensor with sensitivity capability up to 6,400 ISO is probably more than enough.


Therefore, Leica priority was to manage to create a top-notch full frame sensor drawing the maximum possible image quality of world class M lenses like the Summicron-M 28 mm f/2 ASPH, Summilux-M 35 mm f/1.4 ASPH, Summicron-M 35 mm f/2 ASPH, Summilux-M 50 mm f/1.4 ASPH, Apo-Summicron-M 50 mm f/2 ASPH, Apo-Summicron-M 75 mm f/2 ASPH, Apo-Summicron-M 90 mm f/2 ASPH and others.


And the clues suggest that CMOSIS firm has risen above itself.


To achieve a state-of-the-art full frame sensor combining the maximum resolving power and contrast technologically feasible, with an unprecedented dynamic range in the sphere of the 24 x 36 mm digital captors, along with an amazing colour depth and accuracy, it all complemented by a remarkable acutance, was the only way for Leica and also for CMOSIS, STMicroelectronics and some small German technological concerns, which have shared strenuous efforts manufacturing different components of the new 24 megapixel Max COMOS image sensor, because working for a firm with the prestige of Leica Camera Ag was for all of them a unique oportunity to avail themselves of.


This way, if the Leica M9 has been enduring things very well for three years with a 18 megapixel CCD Kodak KAF-18500 (greatly thanks to the unmatched quality of the Leica M ASPH lenses), the new Leica M featuring a 24 megapixel Max CMOS (made accoring to very stringent specifications given by Leica, emulating to the utmost the image quality of the cream of currently existing CCDs, but greatly increasing the performance at high isos up to 6,400 and simultaneously making possible the full HD 1080 video recording), there can be little doubts to have the certainty that the new 24 megapixel Leica M in association with the Maestro ipm and the Leica M ASPH lenses, will deliver a much sharper and detailed image than the Leica M9 and M9-P, together with exceptional tonal range and acutance, perhaps approaching in colour to the results obtained in black and white by the Leica Monochrom.


THE BEST AND MOST COMPLETE DIGITAL FULL FRAME LEICA M EVER MADE
Though its great capability to accept vast majority of Leica R Lenses will be a highly esteemed feature of this camera, we mustn´t forget that first and foremost it is a digital full frame 24 x 36 mm Leica M rangefinder camera, truly the best ever and with difference the most complete manufactured hitherto, increasing the capabilities and scope of the Leica M System to incredible levels which will consolidate the Leica M Full Format Digital System even more, getting high marks in spheres like Full HD 1080 Video, Live View, built-in GPS in the M handgrip, EVFs and many other new features.



Fifty-eight years after the launching into market of the Leica M3 designed by Willi Stein, which marked the beginning of the Mirrorless Leica M Rangefinder System, 

 Daniel Zirinsky, an authority on Leica topics. He has been a photographer with Leica screwmount and M cameras for sixty-four years since 1948. Born in 1927, he was one of the first users of mirrorless full frame Leica M System of Cameras and Lenses in mid fifties, just after the launching of the Leica M3 in Photokina Köln 1954, and he has got one of the best Leica Literature libraries in the world, including original instruction books and information on the rarest cameras given to him by Ernst Leitz III. Here he appears with a Leica 1 Model C Standard Mount from 1931 (the first full frame compact mirrorless camera with interchangeable lenses in the world, thanks to a lens mounting flange to film plane distance fixed at 28.8 mm) with Leitz Elmar 5 cm f/3.5 and solid leather case. The new 24 megapíxels Leica M just presented is the opto-mechanical and versatility quality pinnacle of the compact mirrorless full frame cameras with interchangeable lenses, whose history began in 1931. Photo: José Manuel Serrano Esparza  

and three after the inception of the Leica M-9, the first digital full frame Leica M camera in history, the legendary German photographic firm has just presented the new Leica M featuring a 24 megapixel Max CMOS image sensor

The new 24 megapixel full frame Leica M with Summilux-M 50 mm f/1.4 ASPH lens. This pinnacle model of the M series camera history goes on featuring the core of it: an exceedingly  accurate masterpiece RF 0.68x optical viewfinder, which will keep on being the focusing method for Leica M lenses. On top of the camera and attached on the hotshoe, we can see the EVF Visoflex, which enables the use of top-notch Leica R lenses, including the ones featuring the longest focal lengths. Just under the white letter M, slightly on the right, we can see the Focus Peaking Button activating the Live View 10x magnification option enhancing the subject and contours through a nifty device biased for the most contrasted zones, whose borders are emphasized with red colour to achieve a highly accurate focus with Leica R lenses.

and including a number of new significant features and improvements like the possibility of using the very wide range of top-notch Leica R lenses between 21 and 800 mm, Full HD 1080 video recording, Live View with an exceedingly accurate 10x zoom enabling a very precise focusing with medium and long tele lenses, Visoflex EVF, multifunctional handgrip enabling a very comfortable handling shooting handheld with long focal distance Leica R objectives, GPS, bright framelines for each M coupled lens through a highly sophisticated system of illumination with LEDs similar to the one used by the Leica M9 Titanium, and others.

Only seven years ago, in 2005, it was absolutely unthinkable the very significant leap in quality and versatility of Leica M System which has just taken place with the appearance of the new mirrorless full frame 24 megapixel Leica M, clearly setting up the beginning of a new stage in a photographic system that has proved its capabilities for almost sixty years, amd which is the most enduring photographic system along with the Nikon F one created by Masahiko Fuketa in 1959.


As a matter of fact, the presentation party of the new 24 megapixel Leica M in Cologne (Germany), during the previous day to the opening of Photokina 2012, was full of symobolism and history, and became a homage to a photographic system which with its great qualities (and limitations that also sports) has captured many of the most glorious pages in the History of Photography, and moments of deep emotion were lived, with the presence of Kim Phuc, Barbara Klemm, Nick Ut, Steve McCurry, David Burnett, Sara T´Rula, Anthony Suau, Jens Steffen Galster, Matthias Frei, Thorsten Overgaard, Birgit Krippner, Andreas Kaufmann, Alfred Schopf, Stefan Daniel, Christian Erhardt, Kelsey Fain, Jesko von Oeynhausen, David Farkas and many other personalities related with Leica brand and its history.


LIVE VIEW
Thanks to this function, activated through a specific LV button for it located on the back of the camera,  photographers equipped with the new Leica M will have access to utterly new photographic chances, being able to take advantage of the remarkable performance of both Leica M and R Lenses, going far beyond the capabilities of rangefinder M photography.

Besides, the Live View zoom option enables 10x magnification, with a highly useful Focus Peaking function activated through a round button placed on the front of the camera, just under the white M letter, slightly on the right, which highlights the subject and its contours to help to attain an exceedingly accurate focusing.


It is true that the focusing accuracy with the rangefinder of the camera with Leica M lenses is excellent, but the possibility of using correct focusing confirmation on the screen on using the Leica R lenses (specially medium range lenses and long teleobjectives between 180 and 800 mm) coupled through a special Leica adapter, is very helpful.

Apo-Macro-Elmarit-R 100 mm f/2.8, featuring 8 elements in 6 groups. A genuine Double-Gauss design taken to the limit and one of the best lenses ever made, delivering an amazing resolving power and contrast, being currently one of the world benchmarks in that regard, also boasting an oustanding mechanical construction.

Lenses like this were made to professionally being used for many decades of flawless working. 


Apo-Telyt-R 400 mm f/2.8 featuring a multiconfiguration design with 10 elements in 8 groups, integrated in a front group with 4 elements, a central group with 3 elements and a third group with 5 elements. Real Leica R optical and mechanical jewels like this will greatly extend their working life in synergy with the state-of-the-art 24 megapixel full frame Max CMOS image sensor of the new Leica M and the Visoflex EVF inserted in the hotshoe.

The APO Telyt system consists of three different focusing modules and two lens heads. They are connected via a locking bayonet fitting which attains the adequate alignment. Attaching the smaller head, you can use the focus modules to create a 280 f2.8, 400 f4, and 560 f5.6, while attaching  the larger head you can get a 400 f2.8, 560 f4, and 800 f5.6
This way, the Leica M turns into the craved solution for the full digital integration of the Leica R legendary objectives, which achieved their maximum opto-mechanical quality levels during the stage of the great team of the Leica Camera AG Office of Optical Design directed by Lothar Kölsch and which included some world class optical designers like Sigrun Kammans, Horst Schröeder and Peter Karbe from 1990, with the setting up of a competence center for aspherical lenses technology in Solms (Germany). 

A new digital life has just begun for the legendary Leica R lenses, and the Live View will enable the photographers handling the new full frame 24 megapixels Leica M camera to compose using the real image made by the lens, with utter control of depth of field, exposure, accurate framing and exceedingly precise focusing with the Live View Focusing choice, with the invaluable help of the 3 " TFT screen allowing a very thorough evaluation of the subject seen through the lens, and the flawless expansion of the system into macro and medium, long and very long telephoto domain, until now out of reach of the Leica M System 


EXTENDED HIGH SENSITIVITY UP TO ISO 6400
This is another of the most important sides of the new Leica M, because the Leica M9 and M9-P are able to get impressive image quality between ISO 160 and 1250, and very good at ISO 2000 ( as proved by Brian Bower) if the exposure is accurate, but the tremendous improvements made by Canon, Nikon, and Sony with their full frame sensors at high sensitivities have made Leica (among other factors) to change the three years old Kodak KAF-18500 CCD for this brand new and far superior state-of-the-art 24 megapixel Leica Max full frame 24 x 36 mm sensor, which from now on will be a key element in synergy with the Maestro ipm and the Leica M aspherical lenses to probably deliver the best existing image yielded by a full format digital camera along with the also mirrorless compact Sony RX1 and its state-of-the art CMOS Exmor 24 megapixel sensor with Bionz ipm.

Apo-Telyt-R 280 mm f/4 featuring 7 elements in 6 groups, the best long telephoto lens in the range 280-300 mm ever made, with a potential of brutal resolving power around 260 lines/mm which goes far beyond the capabilities of Kodak Technical Pan, Adox CMS 20 and Argenti Nanotomic-X  b & w films. It is better at f/4 than the extraordinary Canon 300 mm f/2.8 IS II, Carl Zeiss Tele-Apotessar T* 300 mm f/2.8, AFS Nikkor 300 mm f/2.8 G ED VR II and Olympus Zuiko Auto-T 350 mm f/2.8 ED-IF. The chance of using the new full frame 24 megapixel Leica M (which weighs 680 g, id est, 110 g less than the Leica R9 - 790 g, featuring measures of 158 x 101 x 62 mm- and much smaller in dimensions -139 x 42 x 80 mm - ) with its state-of-the-art 24 x 36 mm Max CMOS image sensor connected to this wonder of optical and mechanical design (diffraction limited at f/5.6, and delivering better image quality at f/4 than at f/8) for handheld or monopod shooting at high isos without the reflex mirror bump, with a much lesser camera shake and trepidation than dslr full frame cameras, bringing about higher sharpness in the pictures on photographing both with the Apo-Telyt-R 280 mm f/4 and the rest of Leica R long teleobjectives and zooms, could be something really greatAnd the Leica Apo-Extender-R 1.4 x attached to the Apo-Telyt-R 280 mm f/4 makes possible to have a very high performance 400 mm f/5.6 lens coupled to the new Leica M. 

Needless to say that the possibility of using the Leica M and R aspherical lenses of different focal lengths shooting handheld with the new full frame 24 megapixels Leica M camera at high sensitivities up to ISO 6400 with hardly any degradation in image quality, can be a relish and will open new chances of making photographs in extremely dim environments without using flash and keeping the genuine atmosphere of the location and moment.

VERY STURDY CONSTRUCTION TO ENDURE A HARD PROFESSIONAL USE
The Leica M is a truly professional workhorse, manufactured with the most noble metals, mainly magnesium alloy in most of the body, reinforced by brass on top and bottom plates.

Besides, the camera is very well protected against moisture, dust and rain, with rubber seals, clearly beating in this regard the Leica M9 and M9-P.


3 INCH AND 920,000 PIXELS LCD SCREEN 
Back view of the new full frame 24 megapixel Leica M camera. On top right we see the knurled thumb dial (which can be used after pressing the front Focus Peaking Mode button located under the M white letter of the camera front and the LV key on top left of the 3 inch TFT screen). As we progressively turn it, we´ll be increasing the magnification until reaching 10x magnification. To use this focusing method with highly luminous amazing Walter Mandler´s designs like Noctilux-M 50 mm f/1 and Summilux-M 75 mm f/1.4 highlighting the photographed subjects and rendering amazing bokehs could be something perfectly attainable with a control of both focusing accuracy and depth of field much higher than what was possible hitherto with Leica M cameras. 

It is another of the significant new features of the new full frame Leica M, being made from special hard anti-scratch Gorilla Glass.

LED ILLUMINATION OF THE BRIGHT-LINE FRAMES IN THE VIEWFINDER GREATLY INHERITED FROM THE LEICA M9 TITANIUM
The new Leica M with 24 megapixel full frame Max CMOS has a further significant feature greatly inherited nothing less than from the Leica M9 Titanium: the LED illumination of the bright-line frames in the viewfinder. 



This way, the Leica M brightline frames in the viewfinder for lenses of different focal lengths are illuminated with LEDs, showing in red or white colour the frame lines of a specific focal length - the one of the attached lens at every moment- , instead of showing the frame of two focal lengths at the same time once a specific lens is attached or previously by means of a frame selector lever as happens with the Leica M-9 and M9-P.

In the same way as happens with the Leica M9 Titanium (whose LED lit framelines were only in red), in the new Leica M the focal lengths are read by means of an electronic system based on an artificial luminous source sporting red or white frame lines (adapting themselves to the lighting levels of every place) illuminated by LEDs which have replaced the traditional window introducing natural light that projected in pairs within the viewfinder with the framing lines corresponding to lenses of various focal lengths thanks to a complex system of masks, whose origin dates back to the viewfinder patented in 1941 by Willi Stein with bright-line frames and founded upon the second Albada Principle, a flat semitransparent mirror featuring a collimation lens for the bright-line frames which combines with a prism telescopic rangefinder. 


A HISTORICAL PHOTOKINA
In spite of the widespread economical crisis, in my viewpoint this Photokina 2012 has been very interesting, with four milestones which have clearly marked the largest and most important photographic fair in the world:

a) The presentation by Sony of the excellent RX1, the first digital full frame camera with fixed lens in history, featuring a great beauty of lines and a state-of-the-art 24 megapixel CMOS Exmor featuring a great resolving power and contrast, along with a superb tonal range and colour depth.


b) The presentation by Leica of the new full frame 24 megapixel Leica M, featuring a comprehensive array of  new functions and capacities which outstandingly increase the scope of Leica M System, including the sphere  of HD 1080 full digital video recording of very high quality, as well as enabling the coupling of Leica R lenses.


c) The presentation by Nikon of the full frame dslr Nikon D600, with a remarkable price/performance ratio and an excellent 24 x 36 mm CMOS sensor featuring huge capabilities at high and very high isos.


d) The presentation by Canon of the full frame dslr Canon 6d, which together with the Nikon D600 may have meant a turning point from which there will be a generalized price drop of full frame dslr cameras as a market trend.

SONY RX1: EL GIGANTE JAPONÉS ENTRA UNA VEZ MÁS EN LA HISTORIA POR LA PUERTA GRANDE

José Manuel Serrano Esparza
ENGLISH

Sony Corporation acaba de presentar la Sony RX1, primera cámara compacta digital full frame 24 x 36 mm (sensor estado del arte CMOS Exmor de 24 megapíxels con muy avanzado ipm BIONZ y capacidad de generar excelentes archivos RAW de 14 bits) con óptica fija de la historia y bellísimas líneas que aúnan lo más clásico de las míticas Leicas M analógicas y digitales de 35 mm y la estética moderna y soberbios acabados metalizados propios de los productos electrónicos de la firma japonesa, que es desde hace ya muchas décadas uno de los referentes mundiales indiscutibles en calidad y durabilidad de sus productos, demarcación de tendencias, sabia elección de las líneas de mercado, y muy especialmente originalidad e innovación.




GÉNESIS CONCEPTUAL DE UN PRODUCTO DE ÉLITE
Sony, una de las más importantes empresas del mundo en el ámbito de la electrónica tanto de consumo como desde un punto de vista de investigación, sabe muy bien cuales son los dos patrones históricos en el ámbito de cámaras compactas mirrorless full frame 24 x 36 mm de muy pequeño tamaño y peso productoras de imagen fotográfica de la más alta calidad, acompañada de incontestable excelencia mecánica y fiabilidad:

a) Leica con sus cámaras mirrorless telemétricas full frame 24 x 36 mm con captor analógico en montura de rosca de los años treinta, cuarenta y cincuenta (con ADN Oskar Barnack como las Leica II, Leica III, Leica IIIF, Leica III G), mirrorless full frame 24 x 36 mm analógicas con captor analógico, montura de bayoneta M y ópticas intercambiables de los años cincuenta, sesenta, setenta, ochenta, noventa y última década del siglo XX (con ADN Willi Stein, como las Leica M3, Leica M4-P, Leica M6, Leica M7, etc) y mirrorless digitales full frame 24 x 36 mm con montura de bayoneta Leica M y ópticas intercambiables (Leica M9, M9-P, M9 Titanium y M9 Monochrom).

b) Nikon con sus cámaras mirrorless telemétricas full frame 24 x 36 mm analógicas y ópticas intercambiables de los años cincuenta (Nikon S, Nikon S2, Nikon SP, Nikon S3) así como la Nikon S3 Millennium Serie Limitada de 2004.

El gigante japonés de la electrónica, a la vanguardia mundial de muchos productos digitales, tanto en el segmento de ocio doméstico como en el sector high end más profesional de audio/video, y cuyo producto más innovador durante los últimos tres años - junto con la recién presentada RX1- ha sido el Visor Personal Sony HMZ-T1, ha realizado un importante y muy significativo movimiento, reconociendo con tácita humildad la histórica superioridad de Leica y Nikon en el segmento de cámaras fotográficas compactas full frame 24 x 36 mm, y ha diseñado y construido una bellísima cámara digital compacta full frame 24 x 36 mm, de líneas claramente inspiradas en Leica y que gracias a un esmeradísimo esfuerzo de diseño intentando por todos los medios ofrecer un producto moderno a más no poder pero de estética inequívocamente retro, ha conseguido crear un cuerpo de cámara que constituye una espectacular síntesis entre las formas de la Leica UR 1913, la Leica ´0´de 1923-1924, la Leicaflex 18 x 24 mm diseñada por Helmut Müller en 1962 y la Leica - H 18 x 24 mm (de la que se construyeron en 1965 tres prototipos) diseñada por Adam Wagner en 1964 por un lado y los paneles superiores de las míticas cámaras telemétricas Nippon Kogaku Tokyo formato 24 x 36 mm de los años cincuenta.

CÁMARA COMPACTA PROFESIONAL FULL FRAME 24 X 36 MM CON ÓPTICA FIJA
Hasta la fecha, han sido muy pocas las cámaras compactas digitales aparecidas en el mercado y que pudieran ser calificadas como profesionales (Fuji X-100 formato APS-C con óptica fija, Fuji X-Pro 1 formato APS-C con ópticas intercambiables, Leica X1 formato APS-C de óptica fija, Leica X2 formato APS-C con óptica fija) tanto por calidad de imagen producida por excelentes objetivos como por construcción mecánica, beneficiadas además por una notable mejora progresiva en la calidad de los sensores digitales (especialmente en lo tocante a su rendimiento en isos altos) y de los DSPs, todo ello acompañado por la posibilidad de hacer ampliaciones de muy buena calidad sobre papel fotográfico en tamaños 30 x 40, 40 x 50, 50 x 70 e incluso 1 metro, algo impensable con cámaras tan pequeñas sólo hace diez años.

No obstante, la llegada de la Sony RX1 abre nuevos horizontes y expectativas en el ámbito de las cámaras compactas de pequeño tamaño y peso y óptica fija, con un planteamiento minimalista a más no poder, pero altamente eficaz y que permitirá sin duda obtener una calidad de imagen superior, propia del formato medio, y tirando a pulso con gran comodidad (Sony ha conseguido la proeza de reducir su peso hasta los 500 g), gracias a tres factores básicos:

a) Un sensor estado del arte CMOS Exmor full frame 24 x 36 mm fabricado por Sony, que es en estos momentos el líder indiscutible en esta esfera tecnológica y que permite disparar a sensibilidades entre ISO 100 e ISO 25.600.

Todos los indicios apuntan a que Sony ha realizado un ímprobo esfuerzo por obtener la mejor calidad de imagen posible a ISOS altos y muy altos, por lo que existe una alta posibilidad de que esta cámara se convierta en uno de los referentes en este ámbito junto con las DSLRs profesionales con ópticas intercambiables de Nikon ( la D3, D4 y D800) y Canon (EOS 5DII, etc).

b) Un soberbio objetivo fijo no intercambiable Carl Zeiss T* Sonnar 35 mm f/2 Aspherical.

c) Un ipm muy evolucionado, que constituye otra de las grandes bazas de Sony con la RX1, ya que a buen seguro reducirá a niveles en la práctica insignificantes el ruido a isos altos y muy altos, en plena sinergia con el captor digital CMOS Exmor 24 x 36 mm, que permite alcanzar ISO 25.000, una cifra ciertamente imponente, pero que no parece vaya a ser meramente nominal a partir de sensibilidad ISO 12.000, sino que será plenamente operativa casi hasta el límite, ya que el know-how de Sony en materia de sensores digitales es excepcional. No obstante, habrá que ver el rendimiento de la opción de ISOS ampliables hasta sensibilidades de ISO 50.000 y 102.400, que se antojan ciertamente descomunales.

d) La propia naturaleza minimalista de la compact concept camera Sony RX1 full frame 24 x 36 mm es precisamente lo que permite optimizar todos y cada uno de los distintos parámetros que han de converger para conseguir una gran calidad de imagen, ya que la totalidad del sistema se aplica para el tamaño y características óptico-mecánicas de un sólo objetivo: el Carl Zeiss 35 mm f/2 y su perfecta simbiosis con el sensor CMOS Exmor full frame 24 x 36 mm, lo cual permite reducir en gran medida las aberraciones ópticas y cormáticas residuales, la distorsión, el viñeteado, etc.

En otro orden de cosas, es muy importante tener muy claro que la Sony RX1, pese a no poder utilizar ópticas intercambiables, es una cámara totalmente profesional, tanto por la impresionante calidad de imagen que sin duda conseguirá, como por su excelente construcción mecánica en aleación de magnesio.

En este sentido, conviene recordar que desde una perspectiva diacrónica, han existido soberbias cámaras profesionales de óptica fija tanto full frame 24 x 36 mm tanto en el ámbito del formato 35 mm (Ricoh GR-1, Konica Hexar AF, Nikon Ti y otras) como de formato medio (Fuji 6 x 4.5 cm, Fuji 6 x 7 cm, Fuji 6 x 9 cm, Fuji GA645 AF y otras).

Parece claro que desde el punto de vista de la calidad de imagen obtenida, la Sony RX1 estará intimamente relacionada con las cámaras analógicas sin espejo de formato medio y fácil tiro a pulso, y sus resultados serán comparables a una Fuji Texan Rangefinder 6 x 7 cm tirando sin trípode ni monopié, pero con mucho menor peso y volumen, con las enormes ventajas que ello supone.

Por tanto, la Sony RX1 es una cámara compacta digital profesional, con una concepción minimalista pero eficaz a más no poder, basada en el trío sensor estado del arte full frame CMOS Exmor 24 x 36 mm / excelente ipm Bionz / objetivo Carl Zeiss T* Sonnar 35 mm f/2 Aspherical construido ex profeso para sinergizar al máximo posible con el sensor y el ipm.

DIMENSIONES Y PESO
Sony ha hecho un notable esfuerzo por reducir al máximo posible el volumen y peso de la RX1, que con sus dimensiones de 113 x 65 x 70 mm (la última de las tres cifras se refiere a la distancia desde la punta del objetivo hasta la zona trasera del cuerpo de cámara) constituye una cámara muy pequeña y ligera tratándose de un modelo full frame, lo cual es un logro relevante, siempre teniendo presente que es una cámara de óptica fija no intercambiable, con las importantes ventajas pero también significativos inconvenientes que ello conlleva.


Por su parte, el objetivo Carl Zeiss T* Sonnar 35 mm f/2 Aspherical de 8 elementos en 7 grupos, con tres superficies asféricas, es de dimensiones y peso más reducidos que el Carl Zeiss T* Distagon 35 mm f/2 de 9 elementos en 8 grupos, si bien su tamaño no posee una miniaturización a la par que el cuerpo de cámara y aparece grande con respecto a él.

VISOR ÓPTICO Y VISOR ELECTRÓNICO OPCIONALES NO INCORPORADOS
La Sony RX1 permite la inserción de dos tipos de visores:



a) Visor óptico FDA-V1K, que se acopla en la zapata de accesorios. Fabricado por Carl Zeiss, su aspecto es imponente y potencia todavía más si cabe el muy espectacular aspecto de la cámara, que rezuma belleza y clase.

b) Visor electrónico FDA-EV1MK de grandes prestaciones, en el que Sony ha utilizado todo su know-how en tecnología XGA OLED. Existe una alta probabilidad de que se trate del mejor visor electrónico aparecido hasta la fecha en el ámbito de la fotografía digital. Se acopla a la zona de contactos electrónicos situados en la zona delantera de la zapata de accesorios, dotada con interface múltiple.

Parece claro que ambos visores, tanto el óptico como el electrónico, permitirán una muy buena calidad de visionado, pero en mi opinión habría sido interesante e importante el que la Sony RX1 hubiera llevado al menos un visor incorporado, a fin de mantener íntegramente el pequeño tamaño de la cámara. Además, el tener que comprar aparte al menos uno de los dos visores disponibles hará que el precio se aproxime a los 4.000 euros.

La inserción bien del visor óptico o del electrónico en la zapata de accesorios de la RX1 aumenta el tamaño de la cámara en aproximadamente un 25%, algo que habría sido evitado mediante un visor óptico o electrónico incorporado (quizá un buen EVF incorporado era la mejor opción), aunque ello habría aumentado el coste de diseño, producción y precio de venta.

POSIBILIDADES DE FUTURA AMPLIACIÓN A UN SISTEMA PROFESIONAL CSC FULL FRAME DE ÓPTICAS INTERCAMBIABLES A PARTIR DEL CONCEPTO SONY RX1
Aunque ha habido algunas especulaciones sobre la posibilidad de que Sony haya creado intencionadamente la RX1 como primera etapa con vistas a la creación de un futuro sistema profesional CSC mirrorless de ópticas intercambiables, no lo creo en absoluto.

En mi opinión, la razón fundamental de la configuración de la Sony RX1 como cámara de óptica fija permanentemente acoplada es muy otra, y en ella radica uno de los principales meollos de la cuestión a la hora de construir cámaras compactas mirrorless full frame 24 x 36 mm, cuyo referente cualitativo óptico-mecánico es con diferencia el Sistema Leica M Digital de Ópticas Intercambiables:

Diseñar y fabricar un sistema fotográfico compacto mirrorless integrado por diferentes objetivos de tamaño y peso muy miniaturizado, de distintas longitudes focales y gran calidad óptico-mecánica, de tal manera que interactúen con una cámara full frame de tamaño también muy pequeño pero sensor grande 24 x 36 mm, y que todos ellos sean acoplables, al estilo del Sistema Leica M Digital 24 x 36 mm mirrorless encarnado por las Leica M9, M9-P y M Monochrome o la Fuji X-Pro 1 (cámara también compacta, de dimensiones muy similares a la Leica M9, y que aún teniendo sensor APS-C produce una calidad de imagen propia del ámbito de las cámaras full frame) es algo de extrema complejidad (muchísimo más difícil y caro de diseñar y construir que una cámara con sensor 24 x 36 mm de óptica fija), que requiere unos enormes costes de producción unidad por unidad, el uso de los mejores materiales y vidrios ópticos disponibles, complejísimas técnicas estado del arte glass blank press (Leica) o de moldeado de vidrio (tal y como hace Fuji con sus ópticas intercambiables para la excelente Fuji X Pro1) de los elementos asféricos y unos parámetros de fabricación prácticamente artesanales, que incluyen controles de calidad muy exhaustivos, con altísimas tasas de elementos ópticos rechazados que no cumplan al 100% las tremendamente exigentes tolerancias de manufactura.

En otro orden de cosas, Sony ha aprovechado un importante factor a la hora de ahorrar costes de producción: la ambivalencia de su sensor CMOS Xmor de 24 Megapíxels, compartido tanto por la Sony Alfa SLT A-99 reflex full frame como por la Sony RX1, con la que además de presentar la primera cámara compacta digital formato 24 x 36 mm con óptica fija de la historia, obtiene una posible plataforma tecnológica que funcionará a buen seguro como banco de pruebas para futuros modelos reflex full frame de ópticas intercambiables de su gama Alfa posteriores a la Sony Alfa SLT A-99.

Por otra parte, una cosa es hacer una cámara compacta full frame digital con óptica fija de muy alta calidad como es la Sony RX1, y otra muy distinta (y muchísimo más difícil de realizar) el diseño y fabricación de cámaras compactas mirrorless full frame telemétricas digitales profesionales con capacidad de acoplamiento de ópticas intercambiables asféricas de calidad incontestable y gran luminosidad como la Leica M9, M9-P y M9 Monochrom o cámaras compactas APS-C sin telémetro como la soberbia Fuji X1 Pro, que aún no alcanzando los niveles cualitativos óptico-mecánicos de las Leicas M digitales, posee unos objetivos verdaderamente soberbios, con un muy meritorio grado de miniaturización, gran luminosidad, AF muy preciso y unos elementos asféricos de vidrios ópticos especiales de muy altas prestaciones y moldeados con gran maestría, tal y como sucede con el Fujinon XF 18 mm f/2 R de 8 elementos - dos de ellos asféricos - en 7 grupos, el Fujinon XF 35 mm f/1.4 R de 8 elementos - uno de ellos asférico- en 6 grupos, el Fujinon XF 60 mm f/2.4 R Macro de 10 elementos en ocho grupos - dos de ellos asféricos - y el anunciado Fujinon XF 23 mm F1.4.

Parece claro que en el ámbito de las cámaras digitales compactas mirrorless, el mejor sistema del mundo en estos momentos es el Leica M mirrorless full frame 24 x 36 mm, seguido del Sistema Fuji X1 Pro mirrorless APS-C, de un nivel cualitativo óptico y mecánico notablemente superior a todo lo existente hasta la fecha en su formato (con excepción de la velocidad de AF), y que pese a albergar un sensor de tamaño más pequeño que el 24 x 36 mm, es tal la calidad de su captor digital, de su ipm y sobre todo de sus magníficas ópticas, que la calidad de imagen que ofrece es más propia del ámbito full frame y le convierten en un muy digno competidor frente a cámaras con sensor 24 x 36 mm, llegando incluso a superar ligeramente en calidad de imagen a algunas cámaras réflex con sensor 24 x 36 mm de gama profesional y superior precio.

Evidentemente, la Leica M9, Fuji Xpro 1 y Sony RX1 son cámaras distintas, en especial la RX1, que quizá constituya a partir de ahora un nuevo nicho de mercado, porcentualmente minoritario pero existente, y Sony posee los recursos financieros y know-how para poder permitirse el lanzamiento de la RX1 asumiendo riesgos, y en este sentido es loable el movimiento emprendido por el gigante japonés de la electrónica.

Pero aún entendiendo que Sony dispone de los recursos económicos, expertise y capacidad de investigación para intentar construir una cámara compacta mirrorless full frame con capacidad de acoplamiento de diferentes ópticas intercambiables, ello supondría unas dificultades de todo tipo geométricamente mayores que las que ha supuesto la fabricación de la RX1, sobre todo en el ámbito de la máxima miniaturización posible de los objetivos para dicha hipotética cámara, y que a la vez tuvieran una luminosidad f/2 o f/1.4 con el mínimo diámetro y longitud de barrilete posible, sin olvidar el hecho muy importante de que sería complejísimo conseguir con objetivos de distinta longitud focal acoplados a dicha hipotética cámara una sinergia integral que pudiera aproximarse a la obtenida por el trío indivisible Carl Zeiss T* Sonnar 35 mm f/2 / sensor 24 x 36 mm Sony CMOS Exmor + ipm Sony Bionz de muy alta velocidad y prestaciones, ya que habría que optimizar el rendimiento para diferentes proyecciones ópticas de distintos objetivos, y aumentarían exponencialmente las dificultades para corregir las aberraciones cromáticas, las distorsiones, el viñeteado, etc.

Tras el hito histórico por excelencia en el ámbito de las cámaras compactas mirrorless full frame 24 x 36 mm que supuso el diseño y fabricación de la Leica M9 con telémetro y ópticas intercambiables en 2009, año desde el que sabemos que sí se puede encajar un sensor de formato completo en un cuerpo de cámara mirrorless full frame de dimensiones bastante comedidas, queda pendiente todavía un segundo hito que constituye a la vez el verdadero y más importante reto: la fabricación de una cámara mirrorless full frame 24 x 36 mm sin telémetro, de reducidas dimensiones y la posibilidad de acoplamiento de ópticas intercambiables (muchísimo más versátil que una compacta full frame de óptica fija), que supondría en mi opinión un punto de inflexión histórico y de tendencia comparable a la creación del Sistema Nikon F por el genio Masahiko Fuketa (que se inspiró en la formidable Nippon Kogaku Tokyo SP mirrorless RF de 1957) en 1959, algo que quizá podría intentar Sony con una futura NEX full frame 24 x 36 mm de ópticas intercambiables o bien alguna otra empresa del sector fotográfico. 

Por otra parte, en mi opinión, no deja de ser curioso el que en el texto del anuncio por parte de Sony de la RX1 el 12 de Septiembre de 2012 en San Diego, se diga que " el Carl Zeiss Sonnar T* 35 mm f/2 acoplado a la Sony RX es una elección versátil para retratos, fotografía de calle y captación de imágenes cotidianas".

No parece que un objetivo de 35 mm sea la mejor opción para retratos, lo cual no significa que no puedan hacerse retratos con él. 

A mi entender, el objetivo de 35 mm, por su carácter de angular moderado y su ángulo de cobertura, es mucho más apropiado para fotoperiodismo (óptica versátil por excelencia en este género fotográfico), street photography, fotografía de viajes y paisajes, mientras que para hacer retratos parecen una opción mucho más apropiada objetivos como el Fujinon XF 60 mm f/2.4 R (equivalente a un 90 mm f/2.4 en formato 24 x 36), el Apo-Summicron-M 75 mm f/2 ASPH, el Pentax SMC-FA 77 mm F1.8 Limited, el Canon 85 mm f/1.2, el Canon 135 mm f/2 L y muchos otros. Es decir, en líneas generales, las ópticas con longitud focal entre 75 mm y 200 mm aproximadamente.

OBJETIVO CARL ZEISS T* SONNAR 35 MM F2
Constituido por 8 elementos en 7 grupos, con tres superficies asféricas, una de las cuales es anunciada como "asférica avanzada", es sin lugar a dudas una óptica de élite, que ha sido diseñada y construída ex profeso para sinergizar al máximo posible con el sensor CMOS Exmor formato 24 x 36 mm de 24 Megapíxels de la Sony RX1.

Por tanto, este Carl Zeiss T* Sonnar 35 mm F2 acoplado de modo inseparable a la primera cámara compacta digital full frame fabricada en el mundo, posee una fórmula óptica distinta al Carl Zeiss Distagon Distagon T * 35 mm f/2 de 9 elementos en siete grupos disponible en montura ZF (bayoneta Nikon F), ZE (montura Canon EF), ZK (montura bayoneta Pentax K) y ZS (montura de rosca M42), un excelente objetivo con gran calidad óptica en el centro, buena en los bordes y bastante aceptable en las esquinas a todos los diafragmas, además de caracterizarse por su baja aberración cromática a f/2 y f/2.8, baja distorsión, muy buen control del coma, bajo astigmatismo y una soberbia construcción mecánica completamente en metal, si bien adolece de cierta presencia de aberración cromática al diafragmar y viñeteado algo más visible a f/2 que otros objetivos de su focal y luminosidad y su peso es de 570 gramos, con una longitud de barrilete de 73 mm, algo perfectamente normal en el ámbito de los objetivos reflex retrofoco, que han de salvar el espejo y por tanto poseen aproximadamente el doble de tamaño y peso que los objetivos Leica M y Carl Zeiss ZM para cámaras compactas mirrorless full frame con telémetro Leica M9, M9-P y M Monochrom. 


Los indicios apuntan claramente a que Cosina Voigtländer, siguiendo muy estrictas pautas de Carl Zeiss Oberkochen, ha diseñado y construido el nuevo Carl Zeiss Sonnar T* 35 mm F2 acoplado de modo permanente a la Sony RX1 con unos parámetros cualitativos ópticos y mecánicos superiores al Carl Zeiss Distagon T* 35 mm F2 en montura ZF, ZE, ZK y ZS, con un nuevo esquema óptico y célula que reduce los elementos a ocho y obtiene un superior rendimiento óptico gracias a que se ha realizado desde cero para sinergizar al máximo con el sensor estado del arte Sony CMOS Exmor full frame de 24 Megapíxels, consiguiendo así una máxima conectividad y eficacia entre el captor digital, el firmware de cámara  y el muy evolucionado y rapidísimo DSP de cámara.


Además, otra muy importante novedad es que se le ha dotado de un obturador central, que permite disparar con bajísimo nivel decibélico así como la sincronización de flash a todas las velocidades de obturación, algo enormemente útil para realizar fotografías con flash de relleno, si bien ello limita la velocidad máxima de obturación a 1/2000 seg.


AUTOFOCUS DE NOTABLE PRECISIÓN
Basado en la detección de contraste, no es un AF de velocidad tan sumamente vertiginosa como las reflex profesionales full frame de Nikon (Nikon D3, D4, D800, etc) o Canon (EOS DS Mark III, Mark IV, etc), pero sí muy preciso, con una gran fiabilidad de enfoque perfecto, factor primordial a la hora de conseguir la mayor fiabilidad posible.

Habrá quien pueda pensar que el hecho de no ser un AF extremadamente rápido puede ser un pequeño inconveniente a la hora de hacer fotos, pero con la Sony RX1, que es en gran medida una Point and Shoot Full Frame Concept Camera, ello no supone un problema en absoluto, porque no es una cámara destinada a la fotografía deportiva o de acción muy rápida, sino a ámbitos como la fotografía de viajes, streeter, paisaje y otros.

Por otra parte, la focal de 35 mm de su objetivo Carl Zeiss T* Sonnar 35 mm f/2, moderadamente angular, gracias a su intrínseca notable profundidad de campo, minimiza notablemente la posibilidad de errores de enfoque, que habría sido más alta con objetivos de mayor longitud focal, si bien a máxima abertura f/2 es donde la precisión del enfoque puede resultar en ocasiones más difícil y puede dar lugar a errores (sobre todo en contextos de baja luminosidad), al ser ya la profundidad de campo bastante reducida y porque un AF por detección de fase no es el sistema más idóneo para conseguir un foco preciso a tan grandes aberturas con un sensor full frame 24 x 36 mm, por lo que pese a conseguir unos resultados bastante aceptables en cuanto a enfoque a los diafragmas más abiertos, en mi opinión la Sony RX1 no alcanzará evidentemente en condiciones de baja luminosidad a f/2 y f/2.8 un porcentaje de enfoques precisos y consistencia de resultados tan elevada como las cámaras telemétricas de formato full frame 24 x 36 mm y enfoque manual, que seguirán siendo la referencia full frame en estos contextos, e incluso con objetivos de mayor luminosidad (f/1.4, f/1.2, f/1.1, f/1 y f/0.95).  

Asimismo, aunque el objetivo de 35 mm permanentemente acoplado reduce el riesgo de trepidación tirando a pulso, quizá habría sido deseable algún tipo de sistema de estabilización de imagen, aunque no creo que ello constituya en absoluto un inconveniente significativo, debido al poco volumen y peso del conjunto cámara objetivo (480 gramos).

El sistema AF con chip de detección de contraste de la RX1 posee 25 puntos de enfoque, que se seleccionan de modo automático o manual, existiendo también la opción AF de punto central, AF flexible, AF de seguimiento, y AF de localización facial.

También existe la posibilidad de enfoque totalmente manual, que se realiza con el aro de enfoque ubicado en el objetivo, y que puede ser muy útil en grabaciones de video HD 1080p de muy alta calidad, jugando con las zonas de nitidez y obteniendo el máximo partido del gran nivel cualitativo del objetivo de la RX1 a f/2 y f/2.8.


VIDEO HD 1080 DE MUY ALTA CALIDAD
La Sony RX1 permite grabar video HD 1080p AVCHD versión 2 a tasas de 60p/i, 50 p/i, 25 p o 24 p. La grabación de video de excelente nivel cualitativo y con la enorme capacidad de foco selectivo a los diafragmas más abiertos que permite el formato 24 x 36 mm, es sin duda uno de los puntos fuertes de la RX1.

Por otra parte, Carl Zeiss ha demostrado sobradamente hasta la fecha que sus objetivos de enfoque manual para cámaras reflex full frame de gama profesional en montura ZE (para Canon EOS digital), ZF (Nikon FX digital) y ZK (Pentax K APS-C) son los mejores para el rodaje de video HD con cámaras fotográficas, gracias a su soberbia calidad óptico-mecánica y la posibilidad de enfoque manual muy preciso que permiten, así como el máximo aprovechamiento posible de los planos de nitidez.

Teniendo en cuenta que el objetivo Carl Zeiss T* Sonnar 35 mm f/2 de 8 elementos en 7 grupos que incorpora la Sony RX1 es de dimensiones y peso más reducidos, y de un nivel cualitativo algo superior debido a la mayor sinergia entre óptica, sensor e ipm que permite una cámara de óptica fija, todo ello sumado a las muy reducidas dimensiones de la RX1 (ligeramente más pequeña que una Leica M9 o Fuji Xpro-1) , la nueva cámara compacta full frame de óptica fija de Sony producirá sin duda video de muy alto nivel.

AUSENCIA DE RUEDA DE VELOCIDADES DE OBTURACIÓN
Ciertamente, la Sony RX1 está impregnada de aspecto retro fuertemente inspirado en las clásicas Leicas mirrorless telemétricas full frame con captor analógico y en menor medida (panel superior de cámara) en las Nippon Kogaku mirrorless full frame telemétricas analógicas de los años cincuenta.

Este aspecto moderno a más no poder y a la vez vintage, con la rueda de selección de modos de disparo ubicada justo a la derecha de la zapata de accesorios, el dial para sobre y sub exposición situado a la derecha del todo de la zona superior de la cámara (con un muy útil rango de compensación + / - 3.0 EV, con capacidad de ajustes en tercios de punto de diafragma) y detalles como la marca indicadora de posición de plano focal situada justo a la izquierda de la zapata de accesorios, el clásico aro de diafragmas ubicado en la parte trasera del objetivo, así como el zócalo con rosca para cable disparador del botón liberador del obturador 
son aspectos que potencian notablemente la de por sí espectacular belleza de líneas de esta cámara con la que Sony ha realizado otro importante hito histórico.

No obstante, en mi opinión, la ausencia de rueda para selección de velocidades de obturación sobre el panel superior de la cámara (que hubiera potenciado todavía más el clasicismo de líneas de la Sony RX1) es un error de diseño que ralentiza la producción fotográfica, ya que obliga al fotógrafo a entrar en un menú para acceder a la posibilidad de seleccionar a voluntad las velocidades de obturación conforme al contexto fotográfico.


PANTALLA TRASERA LCD DE ALTA RESOLUCIÓN DE 3 PULGADAS
Es otro de los aspectos más destacados de la Sony RX1, con una gran calidad de visionado, de lo mejor hecho hasta la fecha, complementada por un menú de nuevo diseño, parecido al de la Sony RX100.

A la derecha de esta excelente pantalla LCD de 3 pulgadas, hay dos diales, el más grande ubicado en la zona inferior, justo encima de los botones Menú y Papelera de Reciclaje, y otro moleteado de menor tamaño, situado en la zona superior derecha de la parte trasera de la cámara (en la que se adentra) justo sobre el  botón AEL.

SONY RX1: THE JAPANESE GIANT MAKES A GRAND ENTRANCE IN HISTORY ONCE AGAIN

By José Manuel Serrano Esparza
SPANISH

Sony Corporation has just presented the Sony RX1, first compact digital camera featuring a full frame 24 x 36 mm (state-of-the-art 24 megapixel CMOS Exmor sensor with a highly advanced BIONZ ipm and ability to generate top-notch 14 bit RAW archives) with fixed lens in history and very beautiful lines which combine the most clasical profile of the mythical analog and digital 35 mm Leicas M cameras and the modern aesthetics and superb metallic finishing typical of the electronic products made by the Iapanese firm, who has been for many decades one of the undoubtable world leaders both in quality and durability of its items, marking of trends, wise choice of market lines and particularly originality and innovation.




CONCEPTUAL BIRTH OF AN ELITE PRODUCT
Sony, one of the most important firms in the world regarding the scope of cosumer electronics and research alike, knows very well which are the two historical quality benchmarks in the sphere of compact mirrorless full frame 24 x 36 mm sporting very little size and weight and yielding the highest quality photographic image, along with unmatched mechanical excellence and reliability:

a) Leica with its mirrorless full frame 24 x 36 mm compact cameras featuring an analog captor in screwmount, a rangefinder and interchangeable lenses from thirties, forties and fifties (bearing Oskar Barnack ADN, like the Leica II, Leica III, Leica IIIF, Leica IIIG, etc), mirrorless full frame 24 x 36 mm with rangefinder and analog captor, M bayonet mount and interchangeable lenses from fifties, sixties, seventies, eighties, nineties and last decade of XX Century (bearing Willi Stein ADN, like the Leica M3, Leica M4-P, Leica M6, Leica M7, etc) and digital mirrorless full frame 24 x 36 mm with M bayonet, rangefinder and interchangeable lenses (Leica M9, M9-P, M9 Titanium and M9 Monochrom).

b) Nikon with its analog mirrorless full frame 24 x 36 mm cameras with rangefinder  and interchangeable lenses from fifties (Nikon S, Nikon S2, Nikon SP, Nikon S3) along with the Nikon S3 Millennium Limited Series from 2004.

The Japanese giant of electronics, in the forefront of many digital products, both in the domain of home entertainment and the most professional audio/video high end sector, and whose most innovative item during the last three years - together with the just announced RX1- has been the Sony HMZ-T1 Personal 3D Viewer, has made a very important and meaningful movement, acknowledging with tacit humbleness the historical preeminence of Leica and Nikon in the realm of compact full frame 24 x 36 mm cameras, and has designed and built a very nice digital compact full frame camera with lines clearly inspired by Leica, and which thanks to a sttrenuous effort of design trying by all means to offer an exceedingly modern product boasting at the same time an unmistakably retro look, has maneged to create a camera body making up a spectacular synthesis between the profiles of the Leica UR 1913, the Leica ´0´ 1923-1924, the Leicaflex 18 x 24 mm designed by Helmut Müller in 1962 and the Leica-H 18 x 24 mm (of which three prototypes were made in 1965) designed by Adam Wagner in 1964 on one hand, and the top panels of the mythical Nippon Kogaku Tokyo mirrorless full frame 24 x 36 mm from fifties, designed by                  .

PROFESSIONAL FULL FRAME COMPACT CAMERA WITH A FIXED LENS
Until now, very few digital compact cameras have appeared in the market which could be called ´professional´ ones (Fuji X-100 APS-C format with fixed lens, Fuji X-Pro System APS-C format with interchangeable lenses, Leica X1 APS-C format with fixed lens, Leica X2 format APS-C with fixed lens) both because of the image quality obtained by excellent lenses and the mechanical construction, being also benefited by an outstanding progressive improvement in the quality of digital sensors (particularly as to their performance at high and very high isos) and the ipms, it all accompanied by the possibility of making very high quality big enlargements on photographic papers in 30 x 40 cm, 40 x 50 cm, 50 x 70 cm and even 1 meter, something unthinkable with so small cameras only ten years ago.
Notwithstanding, the arrival of the Sony RX1 opens new horizons and expectations in the sphere of compact cameras featuring little size and weight along with a fixed lens, with a greatly minimalist but highly efficient proposal, which will undoubtedly enable to get a superior image quality, typical of the analog medium format, shooting handheld very comfortably (Sony has achieved the feat of reducing the size of the camera body/ lens binomium up to 480 g), thanks to four basical factors:

a) A state-of-the-art full frame 24 x 36 mm CMOS Exmor sensor, manufactured by Sony, which is currently the undisputed leader in this technological domain and which allow shooting at sensitivities between ISO 100 and ISO 25.600.

b) All the hints suggest that Sony has made a strenuous effort to attain the best image quality feasible at high and very high isos, so there´s a high possibility that this camera becomes one of the benchmarks in the full frame 24 x 36 mm scope, though its lack of interchangeable lenses will make it much less versatile than full frame dslr systems with interchangeable lenses from Nikon (Nikon D3, D4 and D800) and Canon (Canon EOS 5DII, etc) and the Compact Mirrorless Leica M Full Frame 24 x 36 mm System also featuring a highly comprehensive array of interchangeable lenses in different focal lengths.

b) A superb Carl Zeiss T* Sonnar 35 mm f/2 fixed lens, permanently attached to the Sony Rx1.

c) A highly advanced BIONZ ipm, which is another of the great traits of Sony with the RX1, since it will surely reduce to negligible levels the noise at high and very high isos, in full synergy with the CMOS Exmor 24 x 36 mm digital captor, allowing to reach ISO 25.000, a certainly awesome sensitivity. It doesn´t seem that it´s going to be nominal to some extent from ISO 12.000 onwards, but utterly operative almost up to the limit, because Sony know-how in regard to digital sensors is exceptional.

Anyway, it will be necessary to check the performance of extended ISOS choice up to sensitiviness of ISO 50.000 and 102.000, which seem to be truly colossal.


d) The very minimalist nature of the compact full frame 24 x 36 mm Sony RX1 camera is precisely what enables to optimize all the parameters that must converge to achieve a great image quality, since the whole system is applied for the size and opto-mechanical features of an only lens: the Carl Zeiss T* Sonnar 35 mm f/2 and

On the other hand, it´s very important to have clear in mind that the Sony RX1, despite not being able to use interchangeable lenses, is an utterly professional camera, both regarding the amazing image quality it will undoubtedly deliver and as to the excellent mechanical construction in magnesium alloy, so there´s a high possibility that this camera becomes one of the benchmarks in the full frame 24 x 36 mm scope, though its lack of interchangeable lenses will make it much less versatile than reflex full frame systems with interchangeable lenses from Nikon (Nikon D3, D4 and D800) and Canon (Canon EOS 5DII, etc) and the Compact Mirrorless Leica M System also featuring a highly comprehensive array of interchangeable lenses in different focal lengths.
Besides, the RX1 is a minimalist but highly efficient camera, based on the trio full frame state-of-the-art CMOS Exmor 24 x 36 mm / top-notch Bionz ipm / Carl Zeiss T* Sonnar 35 mm f/2 built for maximum synergy with both the CMOS and the ipm.

DIMENSIONS AND WEIGHT
Sony has made a strenuous effort to reduce as much as as possible both the volumen and weight of the RX1, which with its dimensions of 113 x 65 x 70 mm (the last of the three figures refers to the distance from the lens tip to the back area of the camera body) makes up a very small and light camera, bearing in mind that it is a full frame model, which is a remarkable achievement, always being aware that it is a camera featuring a non interchangeable fixed lens, with the important advantages but also significant drawbacks it means.


On its turn, the Carl Zeiss T* Sonnar 35 mm f/2 Aspherical featuring 8 elements in 7 groups, with three aspherical surfaces, sports more reduced dimensions and weight than the 9 elements in 8 groups Carl Zeiss T* Distagon 35 mm f/2. though its size doesn´ t feature a level of miniaturization on a par with the camera body and appears large in comparison to it.

This way, with its dimensions of 113 mm x 65 mm x 70 mm and a weight of 480 g with battery is obviously much smaller than full frame dslr cameras like Nikon D800, Nikon D3, Nikon D4, Canon EOS 5D, 5D II, Sony Alfa A900, Sony Alfa A99, and others.

But if a comparison in size and weight is made with the Leica M9 full frame and the Fuji Xpro-1 APS-C, differences reduce significantly:

The Sony RX1 is slightly smaller than the Leica M-9 (weight of 589 g with battery), M9-P and Monochrom, whose measures are 138 mm in width (2.5 cm more than the Sony RX1), 80 mm in height (1.5 cm higher than the Sony RX1) and a similar thickness of around 70 mm from tip of the objective to back area of the body with a Summicron-M 35 mm f/2 ASPH lens attached.

Regarding the Fuji X-Pro 1, with its measures of 139 mm in width (1 mm more than the Leica M9 and 2.65 cm more than the RX1), 81.8 cm in height (1.8 mm more than the Leica M9 and 1.68 cm more than the Sony RX1) and a similar thickness of around 70 mm from tip of the objective to back area og the body with a Fujinon 23 mm f/1.4 lens attached, and a weight of 450 g with battery, it is very slightly bigger than the Leica M9 (both cameras feature almost the same size) and slightly bigger than the Sony RX1

OPTIONAL NON BUILT-IN OPTICAL AND ELECTRONICAL VIEWFINDERS
The Sony RX1 enables the attachment of two kinds of viewfinders:


a) Electronic viewfinder FDA-V1K, coupled to the hotshoe. Made by Carl Zeiss, its appearance is great, and it enhances even more the amazing cosmetic aspect of the camera, which oozes beauty and class.

b) High performance lectronic viewfinder FDA-EV1MK, in which Sony has used all of its know-how in XGA OLED technology. There´s a high probability that it is the best electronic viewfinder appeared till now in the sphere of digital photography, and it is attached in the area of electronic contacts located on the front of the hotshoe, provided with multiple interface.

It seems clear that both viewfinder, both the optical and electronic one, will allow a very good vision quality, but in my viewpoint it would have been interesting and important that the Sony RX1 had included at least a built-in viewfinder, in order to utterly preserve the samall size of the camera. Furthermore, to be bound to buy apart one of the two available viewfinders will make the price tag approach to 4,000 euros.

The insertion of either the optical or the electronic viewfinder in the hotshoe of the RX1 increases the size of the camera in approximately a 25%, something which would have been avoided by means of a built-in optical or electronic viewfinder (perhaps built-in good EVF was the best choice), though it would have increased the design cost, production and market price.

POSSIBILITIES OF FUTURE EXPANSION INTO A PROFESSIONAL CSC FULL FRAME SYSTEM WITH INTERCHANGEABLE LENSES 
Though there has been some speculation on the chance that Sony has created the RX1 as a first stage for the making of a future professional full frame CSC Mirrorless System camera with interchangeable lenses, I don´t believe it at all.

In my viewpoint, the fundamental reason for the configuration of the Sony RX1 as a camera featuring a steadily coupled fixed lens is a very different one, and around it lies one of the main cores of the matter on trying to manufacture full frame 24 x 36 mm compact cameras, whose opto-mechanical quality benchmark is with difference the Leica M System with Intrchangeable Lenses.

Designing and making a compact photographic system integrated by a wide assortment of lenses sporting highly miniaturized size and weight, different focal lengths and a great opto-mechanical quality, in such a way that they interact with an also very small and light full frame camera featuring a big 24 x 36 mm image sensor, and managing to attain that all of them are attachable, in the style of the mirrorless Digital Leica M 24 x 36 mm System embodied by the Leica M9, M9-P and M Monochrome or the Fuji X-Pro 1 (an also compact camera, whose dimensions are very similar to the Leica M9, and which though including an APS-C image sensor yields an image quality inherent to the full frame sphere) is something of extreme complexity (much more difficult and expensive to design than a 24 x 36 mm camera featuring a fixed lens), which requires huge production costs unit by unit, the use of the best materials and optical glasses available, very elaborate  state-of-the-art glass blank press techniques or glass moulding (such as the one made by Fuji with its interchangeable lenses for the excellent Fuji X-Pro 1 APS-C Format) of the aspherical elements and practically handmade making parameters encompassing highly exacting quality controls, with very high rates of rejected optical elements not fulfilling 100% the tremendously stringent tolerances of manufacture.

On the other hand, Sony has taken advantage of an important factor to save production costs; the ambivalence of its full frame 24 megapixel CMOS Xmor, shared both by the full frame dslr Sony Alfa SLT-99 and the Sony RX1, with which as well as presenting the first digital full frame 24 x 36 mm compact camera in history, gets a possible technological platform which will certainly work as a test bed for future full frame dslr cameras with interchangeable lenses of its Alfa range following the Sony Alfa SLT A-99.

On the other hand, one thing is to make a very high quality full frame compact digital camera featuring a fixed lens like the Sony RX1, and another very different one (and much more difficult to implement) the design and manufacture of mirrorless full frame professional rangefinder compact digital cameras with the possibility of attaching them highly luminous interchangeable aspherical lenses delivering second to none image quality like the Leica M9, M9-P and M Monochrom or compact mirrorless APS-C cameras without a rangefinder like the Fuji X-pro 1, which though not reaching the opto-mechanical levels of the digital Leica M cameras and their hugely comprehensive array of M lenses available, has a range of three lenses truly excellent, with a very praiseworthy degree of miniaturization, great luminosity, very accurate AF and feature aspherical elements of special optical glasses boasting very high optical performance and moulded with great mastery, such as happens with the 8 elements -two of them aspheric ones- in 7 groups Fujinon XF 18 mm f/2 R, the 8 elements - one of them aspherical - in 6 groups Fujinon XF 35 mm f/1.4 R, the 10 elements - two of them aspheric - in  8 groups Fujinon XF 60 mm f/2.4R Macro and the announced Fujinon XF 23 mm f/1.4.

It seems apparent that in the scope of compact mirrorless digital cameras, the best system in the world is currently the Leica M mirrorless full frame 24 x 36 mm, followed by the Fuji X-Pro 1 mirrrorless APS-C System, featuring an optical and mechanical quality level much higher than everything in existence till now in its format (with the exception of its AF speed, a bit slow, though highly accurate), and that in spite of including a smaller image sensor than the 24 x 36 mm, the quality of its digital captor, its ipm and above all its great lenses is so high, that the image quality it yields belongs more to the sphere of full frame format, turning it into a very good contender against cameras with 24 x 36 mm image sensors, managing to even slightly beat the image quality rendered by some professional full format 24 x 36 mm reflex cameras with higher price tag.

Evidently, the Leica M9, Fuji X-Pro 1 and Sony RX1 are different cameras, specially the RX1, which perhaps will open from now on a new small but existing market niche, and Sony has the wherewithal and know-how to afford the launching of the RX1, taking risks bearing in mind the present context of the photographic industry, and in this regard, the movement made by the Japanese giant of electronics deserves accolades.

But even understanding that Sony has got the economical resources, expertise and research capability to try to build a compact mirrorless full frame camera able to be coupled to interchangeable lenses of different focal lengths, it would mean difficulties of all kind geometrically higher than the ones solved to fulfill the manufacture of the RX1, above all in the sphere of the maximum feasible miniaturization of the lenses for such hypothetical camera, and that at the same time they featured an f/2 or f/1.4 luminosity with the minimum feasible diameter and barrel length, without forgetting the very important fact that it would be very complex to get with lenses of different focal lengths attached to that camera a full synergy which could approach to the superb one attained by the indivisible trio Carl Zeiss T* Sonnar 35 mm f/2 / Sony CMOS Exmor 24 x 36 mm image sensor + Sony Bionz ipm boasting very high speed and performance, because it would be necessary to optimize the efficiency of the system for a number of optical projections of different lenses, in such a way that the drawbacks to correct chromatic aberrations, distortions, fall-off,
etc.

After the historical per excellence milestone in the scope of compact mirrorless full frame 24 x 36 mm cameras which meant the design and manufacture of the Leica M9 with rangefinder and interchangeable lenses in 2009, a year since which we have known that it is possible to get a full format image sensor inside a body of mirrorless camera featuring very little dimensions and weight, it remains still pending a second landmark design which is at the same time the true and most seminal challenge: the making of a mirrorless full frame 24 x 36 mm compact camera without rangefinder, featuring small dimensions and the capability to be coupled to interchageable lenses of different focal lengths (much more versatile than a full frame compact camera with fixed lens), which would mean in my standpoint a historical and trendy turning point comparable to the creation of the Nikon F System by the genius Masahiko Fuketa (inspired by the formidable Nippon Kogaku Tokyo SP mirrorless RF from 1957) in 1959, something which perhaps could be attempted by either Sony with a future full frame 24 x 36 mm NEX with intercahngeable lenses of different focal lenses or any other firm of the photographic sector.

On the other hand, in my viewpoint, it´s rather curious that in the Sony text of announcement of the RX1 on September 12, 2012 in San Diego, it is said that ´the Carl Zeiss Sonnar T* 35 mm f/2 coupled to the RX1 is a versatile choice for portraits, street photography and everyday shooting´.

It doesn´t seem that a 35 m lens is precisely the best choice for portraiture, which doesn´t mean at all that portraits can be done with it.

I think that a 35 m lens, because of its nature of moderate wideangle and its coverage angle, is much more suitable for photojournalism ( it is the versatile per excellence lens in this photographic genre), street photography, photography of travels and landscapes, while to make portraits are a much more adequate option objectives like the Fujinon XF 60 mm f/2.4R (equivalent to a 90 mm f/2.4 in 24 x 36 mm format), the Apo-Summicron-M 75 mm f/2 ASPH, the Pentax SMC-FA 77 mm f/1.8 Limited, the Canon 85 mm f/1.2 L, the Canon 135 mm f/2 L and many others, generally speaking between around 75 and 200 mm.

CARL ZEISS T* SONNAR 35 MM F2 LENS
It features 8 elements in 7 groups, with three aspherical surfaces, one of which is announced as ´advanced aspheric´, it is undoubtedly an elite lens that has been designed and made from the ground up to synergize as much as possible with the CMOS Exmor 24 x 36 mm image sensor of the Sony RX1.

Therefore, this Carl Zeiss T* Sonnar 35 mm f/2 lens indissolubly connected to the first full frame digital compact camera made in the world, has an optical formula different to the one featured by the 9 elements in 7 groups Carl Zeiss Distagon T* 35 mm f/2 available in ZF (Nikon bayonet), ZE (Canon EF mount), ZK (Pentax K bayonet) and ZS (screwmount Pentax M42), an excellent lens yielding great optical quality in the center, good in the borders and rather acceptable on the corners at every diaphragm, as well as exhbiting low chromatic aberration at f/2 and f/2.8, low distortion, very good control of coma, low astigmatism and a superb mechanical construction entirely made in metal, albeit it suffers from a certain presence of chromatic aberration on stopping down and a vignetting more visible at f/2 than other lenses of its focal length and luminosity, its weight being 570 g, with a barrel length of 73 mm, something perfectly normal in the sphere of non retrofocus reflex lenses, which have to save the mirror, so feature approximately double size and weight than the Leica M and Carl Zeiss ZM in M mount for compact mirrorless full frame cameras with rangefinder Leica M9, M9-P and M Monochrom.

The hints clearly indicate that Cosina Voigtländer, following very stringent guidelines by Carl Zeiss Oberkochen, has designed and built the new Carl Zeiss T* Sonnar T* 35 mm f/2 permanently attached to the Sony RX1 with optical and mechanical quality parameters superior to the Carl Zeiss Distagon T* 35 mm f/2 in ZF, ZE, ZK and ZS mount, with a new optical scheme and cell reducing the elements to eight and achieving a better optical performance manufacturing it from scratch to fully synergize with the 24 megapixel full frame state-of-the-art Sony CMOS Exmor image sensor, getting so maximum connectivity and efficiency between the digital captor, the camera firmware and the highly advanced and quick camera ipm.

Besides, another very significant new feature is that it boasts a central shutter enabling to shoot with an exceedingly low decibel level, along with a flash synchronization at every shutter speed, something highly useful with fill-in flash photography, though it limits the top shutter speed to 1/2000 sec.

It could be thought that since its AF is not extremely quick, it could be a hindrance when making pictures, but with the Sony RX1, which is a Point and Shoot Compact Full Frame Concept Camera (very small for its format but not a pocket camera), it isn´t a problem whatsoever, because it is not a camera intended for sports photography or very fast action, but for fields like travel photography, streeter, landscape and others.

On the other hand, the moderately wideangle focal length of its Carl Zeiss T* Sonnar 35 mm f/2 objective, thanks to its inherent depth field, minimizes to a great extent the possibility of focusing errors, which had been more higher with lenses feturing longer focal lengths from 50 mm onwards.

Likewise, albeit the ateadily attached Carl Zeiss 35 mm f/2 Asph lens reduces the risk of trepidation shooting handheld, it would have perhaps been desirable some kind of image stabilizing device, although I don´t think it is a significant shortcoming at all, due to the little volume and weight of the camera/lens combo (480 g).

The RX1 AF through chip with contrast detection features 25 focusing points, which are selected in an automatic or manual way, baing also available the choice central point AF, Flexible AF, Tracking AF and Face Finding AF.

There´s the further option of utterly manual focusing, made with the focusing ring located on the lens barrel, and which can be very useful in top-notch quality HD 1080p video recordings, playing with the sharpness areas and getting the most of the great quality level of the RX1 lens at f/2 and f/2.8.

TOP-NOTCH HD 1080 VIDEO RECORDING
The Sony RX1 is able to record HD 1080p video AVCHD version 2 at rates of 60p/i, 50 p/i, 25 p or 24 p. The very high quality video recording and the huge capability for selective focus at the widest f stops possible with the 24 x 36 mm format, is undoubtedly one of the strong points of the RX1.

On the other hand, Carl Zeiss has hitherto proved at length that its manual focus lenses for professional full frame reflex cameras in ZE mount (for Canon EOS digital), ZF (Nikon FX digital) and ZK (Pentax K APS-C) are the best ones for the shooting of HD video with photographic cameras, thanks to its superb opto-mechanical quality and the possibility of exceedingly accurate manual focusing allowed by them, together with the great chance of taking full advantage of the sharpness planes.

Bearing in mind that the Sony RX1´s 8 elements in 6 groups Carl Zeiss Sonnar 35 mm f/2 Aspherical lens features more reduced dimensions and weight and its quality level is superior, due to the higher synergy between lens, image sensor and ipm enabled by a fixed lens camera, it all added to the very small volume of the RX1 (slightly smaller than a Leica M9 or Fuji X-Pro 1).

LACK OF SHUTTER SPEED DIAL
The Sony RX1 truly exudes a vintage appearance strongly inspired by the classical analogue and digital mirrorless full frame Leica M cameras with rangefinder and to a lesser extent ( upper panel of camera) by the analog mirrorless full frame Nippon Kogaku cameras with rangefinder from fifties.

This both conspicuously modern and vintage aspect, with the wheel of shooting modes located just on the right of the hotshoe, the dial for over and sub exposure placed on far right of the camera (with a very useful + - 3.0 EV range of compensation, with capability of adjustments in thirds of diaphragm stops) and details like the mark indicating the position of focal plane just on the left of the hotshoe, the classic f stops ring on the back of lens barrel, together with the thread for shutter release cable are sides outstandingly enhancing the already spectacular beauty of lines of this camera with which Sony has accomplished another significant milestone.

Nevertheless, in my viewpoint, the absence of a shutter speed dial on the camera top panel (which would have fostered even more the classicism and beauty of lines of the Sony RX1) is an error of design that slows the photographic production, since it makes the photographer enter a menu to have access to the possibility of selecting at will the shutter speeds according to the photographic context.

3 " LCD HIGH RESOLUTION BACK SCREEN

It is another of the most remarkable features of the Sony RX1, with a great vision quality, within the best done until now in this domain, complemented by a new design menu, just on the Menu and Recycling Waste Peper Bin buttons, and a knurled smaller further one, located on top right of camera back (inside which it enters) just on the AEL button.
