“The GXR/A12 50mm F2.5 Macro is a camera that is fun to use and capable of producing great quality images.”
DPReview has posted their review of the Ricoh GXR, an “interchangeable unit camera system” that swaps both the lens and associated image sensor as an integrated unit. There are a number of units available and each unit is, for all practical purposes, a different camera. DPReview reviews the A12 which has a 50mm F2.5 Macro lens with a 12.3M (23.6 x 15.7mm) CMOS sensor. The camera has a 3.0-in. high resolution (920,000 dots) LCD.
