Has anyone tried to shoot 120 in this camera? I read somewhere that it was possible
I have not tried this but as the only difference between 120 and 220 is the lack of backing paper, and therefore a different position of the pressure plate, then the easiest method would be to use the lens stopped down to give greater depth of field and not worry about it too much.
A more permanent solution would be to remove the taking lens assembly and to pack it out to move the lens slightly further away from the film. i.e. the same distance as the thickness of the 120 backing paper. An obvious way to do this would be by using a gasket made from 120 backing paper.
