Ricoh has announced two new lens units for its unique modular GXR digital camera platform. The P10 28-300mm wide zoom and A12 28mm fast prime lens units each include the sensor and image processor built into the module. These modules slide onto the GXR body, allowing the photographer to change both the lens and sensor to accommodate different photographic situations.

As we have covered before, the Ricoh GXR platform consists of the GXR body and interchangeable lens modules. The platform is unique in that the body does not contain the image sensor or processor. Instead, these are built into the lens modules so that when you change lenses you are changing the sensor and processor as well.

The new zoom module, tentatively named the P10 28-300 mm F3.5-5.6 VC, is an image-stabilized zoom lens with 10.7x magnification (28-300mm equivalent) coupled with a back-illuminated CMOS sensor. If Ricoh uses the same hardware as in its S10 zoom module, look for the sensor to be a 1/1.7-inch 10MP unit. Ricoh says the P10 will feature continuous shooting up to 120fps, RAW image recording, and multi-target AF.

The 28mm fast prime lens module is tentatively named the A12 28 mm F2.5 GR. This module sports a 12MP APS-C size CMOS sensor and a faster processor (the GR Engine III). Ricoh claims the larger sensor will provide higher definition images with smoother tones. The unit also includes a manual focus ring.

The company says the specifications, pricing, and availability are still subject to change, but Ricoh expects to begin offering the P10 in mid-2010 and the A12 in Q4 2010.
