A lot of lenses creep when they get well used. I have found that the rubber-bands they use to bundle asparagus with work quite well as they are also wide.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

If the rubber band is too thick you can put electrical tape around the barrel to add some drag.

See the thread at https://photography-on-the.net …read.php?t=1484​159&page=2 and specifically my comments (response #18) and what others have added relative to the tape fix. Tape works, and it can work well, but in time it may introduce a new and more difficult issue.

A common issue for the first generation so Canon adds a zoom lock on the second.
It's painful when you set everything ready and just before clicking the shutter, the lens slides down.

What I really want from Canon is a focal length lock so I can lock the zoom lens to a fixed focal length, say, 35 mm or 85 mm, instead of zooming it every time to a marked angle.

Like the 100-400 L IS Dust Pump I still have......

I use O-rings instead of rubber bands. Sometimes I use a small one and a large one like on the 15-85. The small one stays in place and the large one rolls in and out of the crease. So it locks firmly when the large O-ring is in place.

As an FYI Canon can tighten the zoom. They did mine when I sent it in for another reason although I thought the zoom tension was OK.

If it is still under warranty, you could send it in. However, while it should at least hold in a vertical position (up or down), walking or riding with it pointing down will get it extended because of the jostling and it will always do that.

So you will have to either find a way of carrying it differently, or try the rubber band.

When I had my EF 24-105 mm f/4L IS USM, it didn't creep to begin with. But after a few years of use, it started to creep when held vertical. Now it has commited electronic suicide, so I replaced it with the EF 24-105 mm f/4L IS II USM, which has a zoom lock at 24 mm. But only there. It's not creeping either, not yet.
The EF 100-400 mm f/4.5-5.6L IS II USM is the only rotational zoom lens I know of, that can (effectively) lock the zoom at any focal range.
