Ricoh GXR body
Above that's the body of the Ricoh GXR, which doesn't have a lens or even an image sensor of its own; it just includes the camera's shooting control interface, the display, as well as the memory card and battery. You can't take photos with the GXR body alone, only view them.

Ricoh GXR with S10 and A12 modules
Ricoh has now released two imaging system modules: the S10 24-70mm F2.5-4.4 VC and the A12 50mm F2.5 MACRO, and this article looks at the A12 50mm F2.5 MACRO module which includes APS-C format 12-megapixel sensor and 50mm-equivalent F2.5 fixed-focus lens.
The A12 50mm F2.5 MACRO module contains a 12-megapixel sensor in APS-C format and a 50mm F2.5 equivalent Ricoh GR lens. This module has a maximum sensitivity of ISO 3200, no optical stabilization, and a closest focus distance of 7cm.

The body design of the GXR inherits many of the Ricoh GX and GR series' The GXR's body design inherits many of the mature elements of Ricoh's GX and GR series and incorporates a more complete control interface, making the GXR a more professional and efficient control experience. The GXR's body is small, so the buttons and dials are on the small side, and the 3-inch, 920,000-dot display is visually appealing. The A12 50mm F2.5 MACRO module's autofocus response is slow, though.

Top of the Ricoh GXR
The GXR uses the parameter dial at the top of the body in conjunction with the directional buttons on the back to control exposure parameter settings, and achieves a similar level of efficiency in controlling the main parameters to that of a professional DSLR. For more convenient control of shooting parameters, the GXR retains Ricoh's signature ADJ. buttons and menus, custom shooting modes, and more. The GXR also adds a direct-display mode, which allows you to control the main shooting parameters on the display with the arrow keys, without having to go into the menu settings.

The Ricoh GXR supports a pre-autofocus function that keeps the frame in real-time focus
In addition, the Ricoh GXR supports video shooting with a maximum resolution of up to 1280X720 pixels, but there is no continuous autofocusing during the shooting process, nor can you manually control the exposure, so the video shooting function is considered very basic. And? Skew Correction? shooting mode and? Recover Files? (to recover deleted photos) are two of Ricoh's special features.

We tested the color of the GXR with the A12 50mm F2.5 MACRO module using Imatest and Colorchecker SG, and the results show that In standard color mode, the Ricoh GXR's imaging is saturated with blue and cyan colors, which are still slightly warm, but much more accurate than the previous Ricoh R and GX series. In auto white balance mode, the GXR's combination is slightly warmer in standard 5000K lighting.

The sensitivity range of the Ricoh A12 50mm F2.5 MACRO module is from ISO 200 to ISO 3200. The A12 50mm F2.5 MACRO module also supports the A12 50mm F2.5 MACRO module, which has no significant advantage over the current mainstream APS-C format DSLRs. Noise Reduction? function, and you can set the starting sensitivity at which the effect is applied, as well as the intensity of the noise reduction effect. Here's a slice of the largest, best-quality image taken by the A12 50mm F2.5 MACRO module at various sensitivities:
From the images above, it seems that the Ricoh A12 50mm F2.5 MACRO module's image quality is quite good, with the image remaining relatively detailed even at the high ISO 3200 sensitivity, and with the noise controlled to a very low level. . The results compare favorably with current APS-C format DSLRs of the same pixel count, and the level of detail and expression of the scene is significantly better than that of small-format consumer-grade models such as the Canon G11 and Panasonic LX3. When turned on? Noise Reduction? function, the image becomes more detailed and smoother, though the sharpness of details is further reduced.

The Ricoh A12 50mm F2.5 MACRO Module achieves optimal resolution at approximately f/6.3 aperture, though from the maximum aperture to the minimum aperture Across the entire range, the A12 50mm F2.5 MACRO images don't float much in resolution in the center portion of the frame, and imaging at full aperture is still relatively sharp. As a fixed-focus lens with a small aperture, the Ricoh A12 50mm F2.5 MACRO module images shape distortion and dark corners well.

Aside from the slower AF speed, we are very satisfied with the shooting experience and performance of the Ricoh GXR with the A12 50mm F2.5 MACRO Module. experience and performance. By default, it produces images with more natural colors than previous Ricoh cameras, and the out-of-focus images from the fixed-focus lens are especially soft, resulting in a comfortable display of layers and space in the image. The APS-C format sensor delivers extremely low-noise images with a wide dynamic range that ensures vivid images, and the impressive optical quality of the GR lenses not only ensures balanced quality across the entire frame of the photo, but also sharp and detailed images in focus. Below are some test samples taken with the Ricoh GXR with the A12 50mm F2.5 MACRO, with the highest image quality and largest size.
IT168 Review Center Opinion: In fact, originally we didn't have a very positive attitude towards the Ricoh GXR, and the key issue was our concern about its purchase cost and future development. However, after a few days of use, I have gradually developed a favorable impression of it, again because of the GXR's professional and efficient control efficiency in a small body, as well as the excellent image quality that makes people fall in love with it. If the cost of purchasing the GXR comes down in the future, and there are more lens modules available, the future of the Ricoh GXR looks promising - after all, this compact yet professional concept is the direction we'll be pursuing in the future. Ideally, if this modular structure and standard of the GXR can attract more manufacturers, it will be an important milestone in the history of digital camera development. In terms of the A12 50mm F2.5 MACRO module alone, it's good enough except for the irritating autofocus speed.
