My father has recently bought a fair amount of Mamiya C33 and C330 parts which means he now has a C330 and C330S. Out of the remaining parts I have put together for myself a C33 with 80mm lens and I have taken the best (least marked) of the C33 focusing screens.
My question is about spacing of the focusing screen. I thought that the 80mm lens was at infinity focus with the bellows at minimum extension. i.e. wound right back to the body, but the focusing screen only shows infinity focus with the bellows out about 2mm.
In between the screen and the body is a black fibre strip with three holes and there are two washers spacing off the other two screw positions.
Am I missing something or does winding the bellows rack right in actually focus past infinity?
