Hmm. I'm a Nikonist, have never paid much attention to tests of Canon lenses. I think that the only Canon lenses I've used are the C-mount 100/2 (superb), a C-mount teleconverter (lousy), and the ones on my fixed-lens Canon S8 cameras (all pretty good).

Your repair guy may have had/seen an abused 50/3.5 FD.
Unless my memory has failed completely, the 50/3.5 FD was well-respected when new. But that was then. This is now and the FD lenses for sale are all used. So if you get one run it through acceptance testing before using is seriously.
