You can do this very easily with a medium format SLR like a Mamiya 645, but to have this available for a 35mm SLR is very interesting.

My Hasselblad 501C is in need of a digital conversion. The problem is the digital backs can set you back $10,000. I know there is a market for the digital conversion of their film camera. The faster such devices become available, the better.
