I've had one for years (with just the normal lens) and I love it! Only my Rolleiflex with f3.5 Planar lens can match the sharpness of the Mamiya's optic. It is just about a perfect camera. If I could change anything I would make it more robust (the film winding mechanism can be broken if you abuse it, just like the old Bronica S SLRs, so wind on slowly) and I would give it at least 1 mechanical shutter speed that was battery independent. Enjoy and please post results!
