Enlighten me. *Does all mamiya 645 lenses work on the AF(D) platform? If so will I get light metering with the manual focus lenses? *How is the 80/1.9? Sharpness, resolution, contrast, can it compare with the 80/2.0 for Contax? Any good example images on short DoF characteristics? *Which wideangles are recommended? *Which tele lens do you recommend for portraiture? Is it worth while getting the leaf shutter one? Do I have to fiddle with the focal shutters to use it? *Can I if I want use a digital back (heresy, I know) with the AF only, or do I have to get an AFD? *What are the differences between the different AFD models? *Handling, how is it compared to a pro SLR? Do I need to training the snatch and the clean and jerk, or is it okay to use handheld for longer periods of time? If you have any other information regarding these cameras, that you might think is essential but often left out, you are very welcome to inform me.
