I have a 65 lens (early version) for my Mamiya Press. It gives a good performance other than suffering from unpleasant vignetting at most apertures. Having read various reviews/opinions no-one has ever raised this problem. I wonder, therefore, whether during its life -and it has certainly had some- the F & R element groups have been unscrewed from the shutter and some shims dropped out and not replaced. I don't know whether there should be any or not; its just a thought.
Has anyone any ideas why this particular lens should perform so poorly?
