On November 10 2009, Ricoh announced the GXR - the World's first interchangeable unit camera system. The GXR's lens, image sensor, and image processing engine are all integrated into an individual camera unit, so the camera body itself does not contain an image sensor, unlike conventional DSLRs. The camera units are then changed by using a slide-in mount system to attach them to the GXR body. Since the image sensor is not exposed when lenses are changed, it's virtually impossible for dirt and dust to get inside. The Ricoh GXR is also the World's smallest and lightest digital camera with interchangeable lenses, even smaller than the Micro Four Thirds cameras from Panasonic and Olympus.
The Ricoh GXR A12 is a new GXR system lens mount unit that accepts Leica M lenses. Introduced in December 2009, the GXR is a revolutionary interchangeable unit camera system in which lenses can be changed by mounting camera units that integrate lens, image sensor, and image processing engine into a single unit. In addition, utilizing its unique ability to accommodate interchangeable units other than camera units, the system can be expanded to include a variety of other devices. The new GXR MOUNT A12 is a lens mount unit made especially for the GXR. Featuring an APS-C size CMOS sensor and a newly developed focal plane shutter, this unit makes it possible to mount lenses such as Leica M lenses, and it provides various types of compensation and correction functions. Here is the summary of a review by ePhotoZine of the Ricoh GXR Camera with A12 Leica M Mount Module, giving it a rating of 4 out of 5:
"ISO noise performance - The camera gives a good range of ISO settings from ISO100 to ISO3200. ISO100 and ISO200 results are very good with low noise and good detail and colour. ISO400 shows an increase in noise. ISO800 shows another increase in noise, although results are still very usable. ISO1600 shows more noise again, but the results are usable with a film-like quality to the noise. At ISO3200 noise is at it's highest and colour drops slightly. ISO3200 images would be best used resized, or converted to black and white for a film style look. Auto White Balance performance - AWB produces images with a yellow cast under tungsten lighting and using the tungsten preset produces much more accurate colours. Under fluorescent lighting the camera produces good results with just a slight colour cast. Detail is good even in the shadow areas.
The Ricoh GXR plus Leica M module costs £250 for the GXR body and £549 for the Lecia M mount and sensor unit, making it £800 for a Leica M Mount digital camera. A real Leica M mount digital camera, such as the Leica M9 or M9-P, would cost you £4,689 / £5115 respectively and due to a full frame sensor have no crop factor. This makes it exceptional value for money, although it's not the only route into using Leica M mount lenses on a digital camera, with a Leica M Mount to Micro Four Thirds mount available from around £19 on eBay and Micro Four Thirds cameras available from around £350, but with a 2x crop factor. The Ricoh GXR with M Mount module is a great camera to use with the camera providing quick shutter response, a good manual focusing display and a solid well designed body. The quick focus lever on the Minolta M-Rokkor lens used with the camera is a great feature and if you have the choice of what lens you want to use then this really helps focus quickly. Image quality is excellent and images have low noise combined with good colour."

"The Ricoh has a 12 MP sensor, the Sony NEX 5n's is 16 MP, and the NEX-7 is 24MP. The extent to which this difference in resolution is important to any user will be a function of that person's particular needs. Certainly for large prints and extensive cropping the more megapixels the better. I have not had a chance to yet compare the GXR-M and the NEX 7..." More »

"Let me reassure you that the focus assist feature, which you must enable in the menus, allows for great critical focusing of M mount lenses. I personally have used the color focus assist, which creates a shimmer to parts of the image, particularly hard edges, that are in focus as one adjusts their focal plane by rotating the focusing throw on their mounted..."

"The Ricoh GXR is quite an amazing camera when you stay out of the menus. The colors from the camera and the ability to use Leica M mount lenses is generally amazing. For the first time one can truly say that they've got a very good use for Non-Leica M mount lenses. This comes from years of people saying, "If you buy a Leica, get Leica lenses."&nbs..." More »

"I like this little camera! It's unobtrusive, easy to carry, sturdy, customisable, and the 12MP sensor performs adequately. The 2 lenses I tried worked nicely, though I would have preferred a faster than f/2.5 aperture on the 50mm. The camera is a bit slow to process images and shot-to-shot times are longish in single-shot mode; for my style of shooting that..." More »

Pity product is discontinued, tkwshan - Aug 18 2013
I have been a long time fan of the Ricoh GXR system. The modular system keeps dust off the sensor and it is compact and light. Image quality is superb when used with the 'A12' modules. As the system is discontinued, with no information whether there will be any replacement, and if so whether the new model will be backwards compatible, I purchased a second body as spare f...
Best User Interface ever. Great camera, buy it now., Streetphotopix - Oct 30 2011
I love this camera. I've used many systems trying to find the perfect street photographer / versatile carry around camera, and this is it. As background, I've used: 1) Nikon - Film system including FA, FM2, FM3a, F3, F100, and Digital, including D90, D5000, D7000. All Nikon gear now sold, except the FM3a for collectors value. 2) Canon - Film system including EOS 3, EOS Elan II,...
Awesome!, NJC - Apr 19 2011
This is my first ever review of a product, from any website. I absolutely love this camera. I spent quite a bit of time researching. Top reasons I purchased (pros): Pros 1) Liked the idea of the modular sensor/lens. 2) Upcoming module that would handle a Leica M lens. 3) All reviews pointed at extra solid construction - I have to agree - its a rock. (but not too...
Great system, macsareback - Dec 17 2010
This is a hidden gem for photographers, this system may be pricey for the lenses with larger sensors, but you can literally store this camera in any bag. It's the most portable SLR system out there, and well built. I recommend to any serious photographer that they get this system. This company takes it users seriously and releases updates for the software as fast as possible....
