Of interest to V system owners is that there is an adapter that allows use of all V series Zeiss lenses (C, CF, CFi, CFE, F, FE) on a Mamiya 645 AFD focal plane camera ...
You lose auto aperture stop down, but gain focus confirmation in the viewfinder (which, BTW is very accurate ), and the natural use of a 645 to shoot in portrait or landscape orientation without removing the back like you do with a Hasselblad square format camera. Plus shutter speeds to 1/4000th ( max sync speed is 1/125th).
Because it is a focal plane camera, no sync cord is needed from the lens to the back.
Mamiya offers the 645AFD-II, 80/2.8 lens and 22 meg rectangle ZD back for under $10,000.
and it comes with Adobe Lightroom (a $300. value). Apparently the ZD back isn't the swiftest loading back out there and it probably isn't a good choice for those who need fast shooting capabilities.
But it does have a dual card slot to shoot to CF and SD cards ... which no other MF back offers (Canon EOS pro digital cameras offer this security feature against card failure when shooting once in a lifetime scenes).
My rhetorical question is what the ZD images would look like using Zeiss glass? Wish I could get my hands on one to test that concept (some of the Mamiya glass is pretty darn good BTW, but lacks that Zeiss look we all love).
