I am probably considering purchasing a Mamiya 7 or 7II, and a 65 mm lens, and I'm looking for some particular advice regarding contrast in mamiya MF lenses. The issue is the following : Uptil now I've been using an old Rolleiflex (2 lenses, planar 2.8) for all my medium format work. I'm using a Focomat IIC and head Ilford 500 to make prints on FB paper (Bergger or Ilford). I must admit that I'm very much pleased with the results, particularely in terms of contrast on the negative itself. OK, usually I send my films to be develpped by a professional lab, I have no time - and not enough experience - to do it myself.It's clear that neg contrast grately depends on the way they develop them, I agree. BUT : when I compare 2 rolls of the same film emulsion devlopped at the same time in the same lab, one being exposed with my rolleiflex and the other with my Leica M6 (and summicron 35mm 2.0 late seventies), the negatives taken with the Leica seem preety much always more contrasted that the ones taken with the Rolleiflex. In the darkroom it's a little bit of a hassle, because then I often have to burn or dodge aeras on almost every print coming from the Leica, but almost never on the ones coming from the Rolleiflex (and that, even by managing the overall contrast with the multigrade head). SO : If the Mamiya lenses appear to be as contrasted as the Leica ones, I might well stick to my old Rolleiflex 'cause printing is a lot easier when the contrast given by the negative is colesest to the contrast accepted by the paper. If anyone has experiences in that direction, I'd be glad to read your comments.
