Lens creep on a 15-85

Mine doesn't have any creep, it's a great lens.

Wow, I'm really surprised some say they have no creep at all? My research shown, from professional reviews, that lens creep on this lens is completely normal from 50mm up. It's the qualilty of glass and weight which contribute to the creep, it falls under it's own weight, as noted on several reviews.

Mine creeps, quite fast in fact, from that point on. It's a great lens none this less.

Heavy UV filter (like B+W) and hood may contribute to lens creep.

I'm a bit confused here. Is this lens supposed to lens creep or not?

If you are spending $900 on a lens which is not supposed to lens creep (and it does), then I'd be insisting on a copy which doesn't.

I think it is a basic physics thing, mine creeps but it doesn't bother me as I'm usually holding the barrel taking the shot in any case.

almost all zoom lenses at some point will suffer from lens creep especially when they are well used. Its a fact in life just like dust inside lenses, even "L" lenses can have dust.

I wonder if anyone has reported zoom creep on the 15-85 when fully zoomed out. There's been plenty of discussion on this site and across the web but even those with a fairly loose version and a lot of creep seem to indicate that its stable when carried and zoomed out to 15mm.

I just purchased a new copy of the 15-85 two days ago. It did not creep at all in the shop, but by later that evening it started to creep. Now with no lens hood, cap or UV filter it creeps from a little above 24 to slightly below 50. With those three items attached it creeps from a little below 24 to above 50. I can live with this, but assume it will loosen up more over time since it is still brand new. I just would like it not to extend from 15mm when I'm carrying it on my shoulder.

In any case, so far at least, it does drop nearly as quickly nor quite as far as the new example tested in the camera labs review. http://www.cameralabs.​com …IS_USM/video_re​view.shtml

Mine, as with others (or a majority) creeps at those focal lengths ONLY when pointed straight up.

Or straight down of course.Thanks. I knew that. I was just wondering if anyone had an example, or knew of one where the creep occurred even at 15mm when being carried lens down. That might be a problem although even if it extends to 50mm while being carried, it wouldn't be much longer than my EF-S 18-200 when zoomed out.

Its amazing how much mine loosened in only 2 days. It seems to have stabilized, but perhaps not. At 45 degrees there is no creep at all.

No, i have yet to see or read of this. I just checked mine again.. pointing straight down.. and slightly shaking it.. it starts around 23/24mm to 60.

Sounds like yours loosened up a bit. In your earlier post in this thread in April you reported lens creep over 30mm. Was your lens new then? The addition of a filter, lens cap or hood (and especially all three) can make a very noticeable difference. Did you test it differently this time around?

Yes i aimed it down.. but this time, i shook it a bit.. to simulate any bouncing movement..walking with it around your neck. I've noticed no difference since my last post. I bought the lens new in Sept 2010.

So you've have it around 16 months. I hope my acts the same. It loosened up so quickly in just a couple of days so I hope the trend stops.

I've had my copy for about 20 months and it does not exhibit any creep. I always have either the hood or a CPL on it. Although I've not needed it, have often wished that Canon would incorporate a zoom lock such as Sigma has on many of their zooms.

Really? You seem to e one of the few lucky ones. Pointing the lens either straight up or down usually shows creep between around 24mm and 50mm for most people. If it holds its position in that range either facing up or down than you may have a rare one. Even a lot of people who hadn't noticed it before realized they had it when they specifically tested for it.
