Why does my lens fall into total zoom, when the lens is pointed to the ground? Is this normal? I realize the weight of the lens makes the camera lean forward when it's on the strap, but should the lens open like that?

Mar 17, 2014 18:58 | #2 It's called lens creep and happens to a number of zoom lenses in varying degrees. The 18-200 has a lock you can use when it it at the 18 mm position, so that it will not creep while you are walking. Gerry

Mar 17, 2014 20:12 | #3 Yep that is normal...and why they put the lock on it. Every time you take a step there is a significant momentum shift when your next foot catches you from essentially falling forward, and the front element, which is the heaviest element in the camera, is on extending part of the zoom and it pulls the zoom out. As long as it is not so loose that you can't use the lens on a tripod at an angle without the zoom shifting then it is pretty much within the normal tolerances. Cameras: 7D2, S100

No, it is not normal for well-made, quality zoom lenses to zoom creep. Yeah, my EF 24-70 MkII is a cheap little piece of junk that shares the exact same design... Gerry

Mar 17, 2014 22:20 | #7 It's part of the design which utilizes an extending front element. The only way to eliminate creep for such a design is more friction and I don't want more friction. All it will do is lead to wear and trouble. Gerry

It is not a design or materials flaw. It is physics. If two parts fit together so tightly that they cannot move, then by definition they cannot move, which would make zooming or focusing pretty difficult. The only zoom I own that does NOT do this is my 15-85. Eventually, it will.

No, it is not normal for well-made, quality zoom lenses to zoom creep. Actually it is normal. Every super zoom creeps to one degree or another and that includes Canon, Nikon, Sigma and Tamron! That's why all the latest versions include zoom locks. Even many standard zooms develop some creep including, as examples, the Canon 28-135, the Canon 15-85, the Canon 17-55, and occasionally even the Canon 24-105. They are all quality zooms. However, of all the lenses I'm familiar with, my copy of the Canon 18-200 has by far the worst creep. It collapses from around 150mm to around 20mm in a heart beat when pointed straight up or straight down, Luckily the closer to horizontal you get the less creep you get. Mark

Any office supply store will sell you a bag of rubber (elastic) bands for a few pennies. Put one over the lens where the zoom ring meets the barrel. No more zoom creep. But you will have a weird looking lens.
