OK, to be honest - I am not about to buy any of these (my wife still recalls the price of the Mamiya 6 .. ), but I have seen some excellent portrait, still life, close-up and documentary work where thin DOF helped to isolate the subject. At the same time medium format delivers smoothness and tones.
So - I am asking - for the photography mentioned above - what medium format SLR with fast lenses would you choose for such photography? Contax 645 + 80/2.0, Pentax 6x7 + 105/2.4, Mamiya 645 + 80/1.9 or something else? For get the price differences.
O know one could take Crown Graphic with Aero Ektar, but let just put that one aside.
I am a happy user of Mamiya 6, but it does has its limitations. And sometimes I would like to try a different approach.
