These points are both generalizations that really don't apply to current generation sensors. > I�f I should choose a new system I might choose the 645D because I�m > not very interested in speed, but in file quality, and after what I�ve > seen of vignetting problems in the 1Ds I�d prefer a system with > telecentric wide angles specialized for the sensors rather than a > system that pushes the technology to allow you to use old lenses. The problem is unlike the relatively new Mamiya 645AF system the 645 lenses are all pretty old designs so I assume many would need to be replaced for optimum compatibility just like what has occurred in the Pentax 35mm lens line.
