Ricoh recently unveiled its GXR Interchangeable Unit Camera System which is the world’s smallest and lightest digital camera with the ability to change lenses. The Ricoh GXR Camera bring innovation to the digital camera industry as it integrates each lens into the camera instead of just adding a lens. Each lens comes with its own image sensor and image processing engine, which means the body itself doesn’t carry a image sensor.

The body also has an image processing engine but no image sensor and has a 3-inch LCD display for photo previewing. The Ricoh Camera body is constructed from cast magnesium and its surface is covered with a corrosion-resistant “pear-skin” coating.

The GXR system uses slide-in mount system to attach camera units to the body and comes with in two different camera units, the GR LENS A12 50 mm F2.5 MACRO and the RICOH LENS S10 24-72 mm F2.5-4.4 VC. The GR LENS A12 50 mm F2.5 MACRO uses a 23.6 mmx15.7 mm (APS-C size) CMOS sensor with 12.3 Megapixel lens while the RICOH LENS S10 24-72 mm F2.5-4.4 VC gets a 10 Megapixel 1/1.7-inch CCD sensor, Smooth Imaging Engine IV, 24mm to 72mm 3x wide-angle zoom and camera shake correction function.
