I like the Pentax 645NII. I hire/rent this camera whenever I need it = often. If I could find one to buy in my area (for the right price), I would. Multiple lenses are too cumbersome. I mostly use standard lenses. In this case the 75mm. AF is not necessary as I often use MF, but like the feature - just in case. I like the large viewfinder, robust feel and the big dials for AP & SS. For my portrait work I also use Hasselblad & Nikon.
