This seems like the most likely cause for the problem, but

a "moved" mirror (surprisingly easy to do...) or a slightly

displaced viewing screen can have the same effect (the

film image of a very distant subject would be sharp with the

lens set at the infinity mark, though the viewing image

would be out of focus...).
