Seiko Epson Corporation ("Epson") has launched the Epson Rangefinder Digital Camera R-D1, the world's first rangefinder digital camera, in partnership with Cosina Corporation. This camera has come out of a collaboration between Epson and Cosina, it supports Leica M mount and L mount with an adapter and has a six megapixel APS size sensor with an output image size of 3008 x 2000 pixels (which sounds to me like the sensor used by Nikon in the D100 & D70). Epson's timing for this announcement is the 2004 Photo Expo to be held in Tokyo between 19th and 21st March.
The camera's CCD is 6.1 megapixels and use Secure Digital card (SD)
