Japan’s Ricoh Co. Ltd. today announced the development of expansion unit for the GXR interchangeable unit camera system,
which went on sale Dec. 18, 2009. The GXR is an interchangeable unit camera system in which lenses can be changed by mounting camera units integrating lens, image sensor, and image processing engine into a single unit. In addition, fully utilizing its unique capabilities, the GXR line will expand to include a variety of devices through the addition of interchangeable units other than camera units.
The GXR line now includes four camera units, but the newly developed unit being announced here is the GXR Lens Mount Unit. According to Ricoh, with this lens mount unit, photographers can mount lenses such as Leica M lenses and use them for shooting with the GXR. The lens mount unit is being designed to make the best use of the optical characteristics of the lenses mounted. It will have as its image sensor a 23.6 mm × 15.7 mm (APS-C size; total pixels: approx. 12.90 million) CMOS sensor, and it will also feature a newly developed focal plane shutter. The lens mount is scheduled for release in the fall.
