I was just shooting out in the snow with my F-1N and pre-S.C. 50/1.4, and a better hood would have helped. I was using the Canon BS-55 hood. I read somewhere, perhaps here on APUG, that a certain square hood works well with Canon FD lenses. Any recommendations? I would be using the hood primarily with the 50/1.4 mentioned above and my 55/1.2 S.S.C. It would be nice if it could also cover my FDn 35/2 and FDn 100/2.8.
