Hi Steve, I doubt it's your EOS 1v body mount. There is some rotational play on all of the lenses but the play seems to get larger on the "L" class glass for some reason. I've tried to isolate this play over the years with several different EOS bodies (EOS 50, EOS 5QD, EOS 1, EOS 1n, EOS 1nRS), I have had access to with several different lenses (EF 15 2.8USM, EF 20 2.8USM, EF 50 1.4USM, EF 85 1.8USM, EF 300 2.8L, EF 400 2.8L, EF 600 4L, EF 17-35 2.8L, EF 20-35 3.5-4.5USM, EF 28-70 2.8L, EF 28-105 3.5-4.5USM, EF 70-200 2.8L, EF 100-300 4.5-5.6USM), I have had access to and the play seems to be most prevalent on the "L" lenses starting with the EF 17-35 2.8L and getting worse as the lenses get bigger up to the EF 70-200 2.8L where the play seems level out to be the same for all larger "L" teles. It's also very noticeable with ordinal type Canon EF 1.4X and EF 2X converters. I have not tried to stack the EF converters as I lack the Canon 12mm extention tube.
