Digital Photography Review has published a preview of the Ricoh GXR MOUNT A12, a new module for the Ricoh GXR camera. Like other GXR modules, the GXR MOUNT A12 inserts into the GXR camera body and provides the sensor and optics for the camera. This particular module combines a Leica M lensmount with an APS-C format 12.2 million image pixel CMOS sensor, allowing the GXR camera to accept nearly all M-mount interchangeable lenses.
