Hasselblads have digital backs for them. The problems is that they cost boat load of cash.

The problem is that a raw CCD/CMOS sensor output generally looks shite. I work at a place that experiments with novel sensors, and we have a device that uses off the shelf CMOS sensors for redacted camera sensors. They are the same type of sensors that are used in previous high end phones. However the raw images just look shit. Part of it is the lens, part of it is that we are not interested in making "good" looking images, but accurate images.
