I'll add: I've shot with Hasselblads before, not extensively, but I never "clicked" with them (sorry). I actually prefer the Pentax 6x7 to the Mamiya 7 in many situations...recently the prices have been increasing but even now it is a very underrated piece of equipment, IMO. The Mamiya is lighter, better for composing, and has aperture priority metering...oh and it's nearly silent and it has leaf shutters so fast sync speeds. I have 55mm and 105mm on the Pentax, and 80mm on the Mamiya...makes a great combo. My biggest beef with the Mamiya and Hasselblad is the lenses are so expensive (can you tell I don't own Leica stuff anymore), I can only afford one, maybe two. With the Pentax I might add on a third or fourth, but I'm quite content with what I have. It's a good system.
