Ricoh GR Digital
From Wikipedia, the free encyclopedia
The Ricoh GR Digital is a compact digital camera. Its distinguishing feature is its fixed focal length lens (non-zoom). First announced at Photokina 2004, it went on sale in Japan on 21 October 2005 at the price of ¥80,000. The GR Digital is Ricoh's digital successor to their popular 35mm GR series film cameras.
