You guys that think I'm worrying are dead wrong. I'm simply gathering information. But it doesn't bother me if you want to spend your time misinterpreting someones post. I'll continue to use my lens just the same.
I am only checking my lens after the info was brought to my attention about movement, not trying to put a damper on anyones post or experience. But I took out all of my lenses just to check them. IS it possible it is wear on the body? I have heard that heavier lenses tend to pull and weaken the ring. Check another lens and see what you get.
