If you're sick and tired of measly 25MP sensors, this CFV-50 Digital Back back from Hasselblad might interest you--it has a sensor twice the size of those in full-frame cameras--50 MP of resolution (6132 x 8176 pixels), and it's compatible with all Hasselblad V system cameras made since 1957. It gives you RAW 3FR files (average: 65 MB/image) that are supported directly by Adobe and Apple, approximately 60 images/4GB memory card, at a capture rate of 1.1 seconds/capture.
A 2.5" TFT 24-bit color display allows you to monitor your images, and you can shoot up to 8 hours using a Sony InfoLithium battery. You have a choice of shooting in the traditional Hasselblad square format (38 MP) or the full rectangular format (50 MP), tethered or untethered. Digital correction is possible using V system lenses, and the CFV-50 is compatible with view cameras with an optional adapter plate.
