I once owned the lens and it creeps from day one, and I also see other copy of 17-85 lenses creep. So I guess it's a rather common phenomenon.


I doubt if there's anything you can do about it rather than just hold it tight when shooting with big angles. My 24-70L after quite some time of use creeps just slightly when zoomed out to 24mm and sit upright.But if it creeps really badly, you may want to drop by Canon service centre and you should be eligible for a free repair especially when the lens is still covered by warantee.


Bottom line is that lens creeping will not affect the image quality, as you may already know.
