Lens creep on a 15-85

You should put it between zoom and focus rings

right between the manual focus ring and the zoom ring. The O ring or rings puts pressure on the chamfered edge where the MM numbers are. In my case, I use the two O rings, one small and one large to bind the zoom ring from moving at all. For that reason, my solution is more like the zoom lock on some of Canon's lenses: the 70-300L for instance, but I can "lock" the 15-85 at any MM setting.
I can't speak for Mark's solution but I think he can still zoom his lens in and out. If that is the case, the O ring(s) provide additional friction and keep the lens from creeping.

thanks folks ~

Correct. It just tightens the creep up a bit. Does not impact the ability to zoom in any way.

95 degrees out in a hot truck it will creep. but now 30 d. now creep.?

Another possible solution is to use two of Goody rubber elastics

Put the one next to another, the benefit is that you can choose colors

I finally pulled the trigger and purchased some Lens Bands from Amazon: http://www.amazon.com/​gp/product/B0050KHY5E/

My Canon 24-105mm had wicked zoom creep, similar to what's been described about the 15-85, and now the problem is solved. Here are some photos of my setup. Let me know what you think.

$8 for that? Try these and have a lifetime supply. We're using them on our 24-105s, 70-300, . . .

I've been using that solution for years.

But, it's not red. And there's no brand name on them . . .

Resurrecting a two year old thread... Ok, let's forgive a new member!

Agree old thread, missed it the first time around, but I actually have something to add.

Had very bad creep with my 28-135 and less so with the 15-85. Instead of the rubber Goody elastics, I think someone on another thread from a while back (2010 or 2011) suggested the plastic Goody elastics,

Not 100% sure these were the ones I got, but the packaging looks familiar.

Had to stretch it over the front element and worked it back to the thin gap between the zoom ring and the lens body. I tucked in part of the diameter of the band trying to leave most of it sticking out. On the attached image, I pushed some of it all the way into the zoom ring space (right half of lens) so you can see how it fits. I checked the band on the 15-85 one after 2 years and did not notice any wear. Took this pic today of the 28-135, has to be at least 3+ years and it still feels "elasticky", i.e. hasnt hardened up. I try to use my finger tips to move it, what I did hear for the pic and to pull it back out.

Just to add an other option:
Silicon rubber bands, that I use for the kitchen. Really high quality rubber bands that don't become brittle over time.

Perfect fit for my lens and put enough tension on to prevent the lens from creeping but I still can zoom easily.

Just thought I'd add this oddity. My 15-85 went from not doing this at all, to dropping from 15 to 85 with a clunk as soon as it is pointed downward. I thought it would progress, or should I say deteriorate, slowly.

I would not call it "deterioration", but rather "failure". If it happened to mine, I would send it in for service.
