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.
That digital back cost so much because that sensor is huge (it matches the dimensions of a medium format film frame) and has a lot of bit depth. That said, I have seen some of the lower megapixel backs come down as higher and higher megapixel backs make it to market.
Speaking of Hasselblad, their top-of-the-line camera sports a 200megapixel back! It is yours for a mere 45 grand.
