I just bought a used 70-200 f/2.8 IS lens, and when mounted on my 50D, even though it "clicks" when mounted, there is a little bit of play after mounting, like it can rotate about 1/16 of an inch in either direction when rotated. All of my other lenses mount fine, with no play at all, never had an issue.
Is this common for the 70-200 IS? I had a 70-200 non-IS about a month ago, and that was fine too, so I know it's not the body.
So being new to this lens, is this common? And I hope I am explaining this well enough to understand.
Thanks all!!!
Ken
