Medium-format camera manufacturer Mamiya, founded in Japan right after the end of the World War II, has today announced two new digital products that offer an impressive resolution of 21.5 effective megapixels.
The Mamiya ZD interchangeable-lens digital SLR and Mamiya ZD Back share the same 48 x 36mm RGB CCD image sensor, exactly twice the size of a 35mm frame. The ZD SLR is styled similarly to the Mamiya 645 AF medium format camera. Other features include a continuous shooting speed of 1.5 frames per second for 11 frames, a user-replaceable low-pass filter, fixed IR cut filter, RAW and JPEG file formats, Adobe RGB and sRGB color spaces, ISO sensitivity from 50 - 400, a 1.8" LCD display, IEEE 1394 and NTSC / PAL video connectivity, and both AC / Lithium Ion battery power sources. Pricing and availability have not been announced at this time.
