How many of you have barrel creep on your lenses and what can you do to fix it? Does this bother any of you?
Depends on the lens. My 24-70 doesn't do it. This off-brand 70-300 I owned did when it was pointed down.
Minor nuisance that didn't bother me enough to worry about it. My 24-70 before it came back from Canon (on a completely unrelated issue) even had some lens "worble" I'll call it (like when zoomed out I could move it a little).
if it's rapid when you point it down like it goes from 105 to 24 WHACK, send it in. If it's just minor creep, don't sweat it.
My 24-105L has not developed any type of lens creep...now if you want to see a "creep" of a lens look no further than the 28-135 IS...That one over time could nearly be considered a T&S lens!!!
It happens on my 24-105. It usually isn't an issue, but once I was shooting a long exposure with the camera pointed straight up and it was a major issue. I don't know what is involved in fixing it.

Tape?
No, seriously, it probably would fix it in your case.
Tape would usually do the trick (it did when I had a 75-150mm series E nikon lens) but the 24-105mm is weather sealed wouldn't the rubber seals provide too much friction?
If it really bothers you THAT much, here's the fix: Peel back the rubber focusing ring and rotate the ring until three (or four) little screws line-up with the access hole on the ring. Those little screws tighten or loosen little teflon spacers that control the 'barrel creep'. If you tighten them (very, very slightly), you should eliminate your barrel creep. Remember, 'less is more' when adjusting the tension on the barrel.
My 4 year old 24-105L is still firm and creepless in normal operation. I suppose if I needed to shot straight up with a tripod (star trails) any zoom would drift. That's why all true photogs carry duct tape! Although I normally use a prime for star trails. On the other hand, my old 28-135 IS was loose as a goose and zoomed just by looking at it sideways...

HTH,
It normally, as I think I wrote, doesn't bother me "that much" - but this looks like it would be worth trying.
I'd classify "creep" as a "minor annoyance" in my case, but I wouldn't might reducing it a bit!
Mine creeped. It drove me nuts! I did not feel like doing the "peel back" myself, so I sent it in to Canon (NJ).
Cost - $120. They totally fixed the creep. In addition to fixing the creep they said "Checked all, adjusted center/tilt/front, back focus & cleaned all factory specs." When I got it back it was WAY off focus (required +10 adjustment). Sent it back in and they fixed it for free.

HTH,
Hey upside down, I remember looking for these on my 24-70, and I couldn't find thme by taking off the focusing ring. Is it different on some lenses? I'm not anxious to figure it out, but curious.

Hey Robert...Let me clarify the procedure on the 24-105; Once you peel back the rubber focusing ring, there is a single (one) access hole on the exposed focusing collar. You have to turn the collar and line-up the adjustment screws one at a time. I'm not 100% that the 24-70 is the same but I'm pretty sure it is. Maybe you missed the access hole on the collar because there's only one hole and you might have been looking for three or four access holes. I know the first time I looked for it on the 24-205 I missed it too. I had to take a second look before I spotted the access hole and realized that I had to turn it to each adjustment screw one at a time.

HTH,
Good fix, Thanks.
Mine doesn't creep yet but like any mechanical tube-within-tube type device it will eventually loosen, I'm sure. I've logged the existence of this adjustment into brain storage (prob'ly better get it on disc).
