I think there really is only one sized sensor and that is the 6x4.5. Actually most are slightly less than a full 6x4.5 frame. There is now one full frame sensor in I think the Phase 65mp back. Look at Badger Graphics to see the specs. Here is a 35mm Apo Sironar http://www.badgergraphic.com/store/c..._detail&p=1528

I bet these things are fantastic with roll film. The longer lenses such as the 55mm should cover 6x7 with movements. I wonder if it matches the Mamiya 7.
