Those of you that love shooting medium format or in black and white will probably really want to take a good look at the new Phase One Achromatic + 39MP medium format digital back. It’s really new and interesting technology and the first commercially available medium format digital back to do what it does. With a 49.1 x 36.8 CCD sensor with no RGB filters, the camera is meant only to shoot black and white images. With ISO sensitivities of 50-800, 12 stops of dynamic range, and a 2.2″ QVGA TFT LCD with 230,000 pixels it seems pretty solid (minus the screen). More about the technology can be read here and see it in action here. The back seems very targeted towards scientific professionals. It seems to be available for $41,990.
