I don't have an 85/1.2 but I do have a Minolta 85/1.4. It's a beautiful lens in terms of bokeh but certainly not sharp at all wide open. Its equivalent on 6x7 would be 170/2.8; I have a 180/4.5. I also have a Sony 50/1.4 (a bit sharper, not half as buttery) and a near perfect equivalent in the RZ 110/2.8. I could do some comparison shots if you like, but beware my scanner is only 2500dpi (50lp/mm) so you won't necessarily see all of the resolution available from the 35mm shots.
