Crop Factor for V96C with Hassel 503CW (and all the others Hassels that have motordrives and can use the digital back) is 1.5X.
Apart of the crop factor, other thing that made me sad about it is to see the comparision between EOS 1DS MKII and V96C somewere.
Altrought Hassel has more color fidelity and a bit more quality, Canon has a noise reduction software that makes your eyes bump out of your face. Looks way better than the Hassel images!
And of course, V96C has to be attached to a hard drive to work!!!
