Well, if one likes the square format and method of shooting, be aware that the CFV/39 and CFV/50 meg backs can be shot square, providing up to a 38 meg square image, and the focusing screen provides dual format markings. No need to restrict yourself to 16 meg.
Phocus software is set up for this square option, and has new digital corrections for most CF, CFi and CFE Zeiss lenses for a level of image quality above the already excellent Zeiss optics.

P.S., when Hasselblad announced the CFV/50 I instantly regretted selling all my V gear. I honestly thought they'd never go that big.
