I have had no trouble with the 55-200.....but as I have read in other places if I barely bump, and I mean barely, my 60mm the front housing snaps out of place and the exposes the interior of the lens somewhat. So far it has happened twice, but I haven't seen any real damage from it. It is terribly unnerving though. As for the decentering issue, this concerns me. So far all of my lenses seem to be close, I hope I am testing them correctly.
