Zoom Lens Creep - Already?

Today for the first time I used my new EF 100-300mm f/4.5-5.6 USM lens at the local zoo. Only after a few hours I noticed the lens zoomed down as I walked with it hung from my shoulder. I have heard about lens creep but thought it only happened as lenses became old. Is this common for this model or did I get a lemon sample? Thank you.

Charles: I don't think you have a lemon, and there does seem to be

some unit-to-unit variation in their tendency for the zoom to creep or

move, but even the most "snug" or tight samples will probably slip

when vertically dangled and jostled about from a neck strap. The two

samples I've used would slip under such conditions, but neither would

slip if I simply held the lens vertically, without jarring it, but if

I walked with either sample as you've described, both would slip to

some extent, and I don't think this is unreasonable for a modestly

priced USM lens. Forget about it, and concentrate on learning to

achieve the sharp images it is quite capable of producing with good

technique.

This is common, don't worry about it.

Charles,

It is quite common and nothing is wrong with your lens.

Agreed it is normal, but it can be a pain sometimes. Does anyone have

a decent workaround to prevent this. Something that doesn't affect

usability or mar the lens body?
