gaopa2 If your new lens is of recent vintage, and doesn't begin to creep after a few outings, then perhaps Nikon has done something to dampen the zoom movement. It would be interesting to compare it to someone else's, if you have a photographer friend that has one, and see if the "freedom of movement" is relatively the same for both lenses. I know mine and my girlfriend's (purchased about 8-months apart) both have creep.
