There is a tiny bit of play when my 70-200 lens is attached to my 5DMKIII....and when I say a tiny bit of play, the lens hardly moves, but it is noticeable. This is my second 70-200 lens (I returned the first lens, because it had dust in it), and both lenses had the same amount of play when attached to the camera body. Is this play normal for the 70-200 lens? It doesn't effect the image quality (attached are a few photos I took with the lens).
By the way, my other lenses (24-105 & 50 f/1.4) attach securely to the camera body and do not move at all.
