I have the 24-70L and it does not creep no matter which angle I hold it. I used it hard over almost two years I had it, hanging on the camera all over the places outdoor when I'm travelling and shooting. Now it has a slight potential to creep just a little bit when positioned up right and zoomed out to 24mm, this happens when I initiate the movement. But overall I think the 24-70L is a quality lens which should not creep at all when used lightly with care.


Plus, the 24-70L is optically superior to the 24-105L IMO.
