I've gone through two copies of this lens and they both have a little movement when attached to the camera body. I have a handful of other lenses lighter and heavier (e.g. 70-200 f/2.8 IS) and they don't have any movement at all. The movement seems to be vertical only, not a side to side thing ...odd feeling (worse with the Kenko tubes on).


I'm wondering if anyone else has felt this play in the lens when attached?
