>>3714542dude you're wrong in almost everything that you wrote.
65mm does not exist in digital, and never did. Arris large format is just two ff sensors glued together, and called FF. You'd have to go to imax film format to get 65mm format.
Hasselblad does not make dslr's. It makes dbacks. Basically they're mirrorless cameras, with an attitude. They're not 65mm either, but are medium format.
