The flagship 'unit' for the Ricoh GXR is a 50mm (35mm equivalent) lens known as the GR LENS. This is the APS-C-sized lens, which has a 12-megapixel CMOS sensor built into it with a crop factor of 1.5. It will cost around $1100 plus GST. This is a prime lens with a maximum aperture of f/2.5 that is capable if capturing images with a wonderfully shallow depth of field. It has a floating lens structure that allows it to also be used for macro photography and Ricoh claims a low level of vignetting in macro and normal shooting modes. It has a manual focus ring.
