The Hasselblad H3DII-31 is a top-notch medium format digital camera. It has a slightly smaller sensor than the H3DII-39, and a little less MP for a slightly lower price. You still get the same 48-bit color depth and the ability to capture images in the industry-standard DNG (Digital NeGative) RAW or TIFF format. The H3DII-31 also has the ability to change between eyelevel and waist level viewfinders and can even work with film for those extreme conditions. It also allows three levels of digital operation and storage.
