1. From my experience a 6x4.5 film scanned with Nikon 9000 is equal a 22 mega pixels back. Is there any reason to use a 22 mega pixels digital back on a Mamia RZ67 IID? Why a digital sensor will outperform a larger 6x7 film?
2. I have a Sinarback 54M with Contax 645 adapter attached to my Contax 645.
How to use a moveable Contax 645 Back (Widepan made in china) attached to Sinar P2 4x5 camera? I'm completely new to moveable backs, are they worth the money? Is this for still life subjects or whatever else?
Should I better buy a 4/16 back, like a Sinarback 54H?
