Hi,
I bought a new 28-135mm lens off the ebay a couple of months ago. I have noticed that from the first day I received
the lens....the front end is very loose. It always extend all the way by it self while I am walking around with the
camera. At first, I thought it was normal since this is my first DSLR and optionl lens. But until last week, my friend
brought in his 40D and the 28-135mm lens. I can tell right away his lens does not loose at all and it will not extend
all the way by it self. And plus he has it for almost a year. So, may be I got rid off from the ebay seller (but it looked
like a new one) Do you guys have this experience when you buy it new? Is anyway I can fix it? I was just wondering
will that affect any picture quality or performance? The seller claimed that it is a brand new took off from the 40D kit.
It comes with a warranty card and grey box in plastic bag.
Thanks.

Yes, I bought my lens new and had that characteristics. You can send your lens to Canon to get it tighten but not sure in your case for warranty.

Check the warranty card for the S/N and see if it matches the lens. Many zooms on this level will "creep". It is very
common. If there is not issue with the lens performance and function, you are most likely fine. By loose I guess you
mean wobble of the barrel. The is common also although I can not tell you why one copy does and another does not.

Yes, I am talking about the plastic barrel. It just kind of bother me while your are walking and the zoom ring barrel extend all the way by it self. I don't have the lens with me but I remember the s/n matches the lens. In that case, do I get any warranty from Canon since I buy it off from ebay in two months ago with warranty card but not in retail box.

I am sure that all Canon needs is that card and a reciept from when you purchased it (proves start of warrenty). Others here would be able to give better insite and if there is a way around your E-Bay issue as I have yet needed to use warranty on any of my nearly 2 dozen Canon purchases.

When you send something to Canon, they look at it first then call you with an estimate. If you refuse to pay they just send it back. You would have to pay for shipping. Some people have had Canon do things free, out of warranty, but its not something you can bet on.
My 28-135 creeps and so far its not a problem.

I think what you are talking about is "zoom creep" which Jason mentioned above. I also own the 28-135 IS. I purchased it new about a year ago and did not notice any zoom creep while walking around, but after a few months it started to loosen up and extend while pointing down. It does not extend all the way, but I bet in a few more months it will. I was told this does not affect picture quality, but it certainly is annoying. Some zooms have a lock switch so that the lens can be locked in its shortest length for walking and travel. If this is your only issue with the lens and the picture quality is good it may not be worth sending it in as it will just do the same in a few more months time.

You're talking about zoom creep. I bought a brand new 28-135 in 1999 and sold it when I got the 24-105/4L IS USM last year. At first, the 28-135 didn't have zoom creep. At the end, it did. I don't recall how long it took to develop it, but it had zoom creep for the vast majority of its time with me. This didn't affect it in any other way; it zoomed properly when in use, focused properly, had no problems with image stabilization, and maintained image quality commensurate with its positioning as a high-end consumer zoom.
If it takes good pictures, you probably needn't worry about it.

It took several years for my 28-135 to develop "zoom creep." Initially it was pretty tight and got loose as a goose with
constant use. After all, it's mostly plastic so things don't stay tight as long as metal mechanisms.
Christina Wiley , Sep 08, 2008; 07:17 p.m.
Mine was a bit loose from the start, and got worse over the last year that I've had it. It's never had a problem popping all the way out when
the camera points down. That, and a few other things like contrast and size make me not overly wild about this lens, and it's probably
going to be replaced in my bag by the 24-105L.
