Finally getting to spend some quality time with my new acquisition
(EOS10D 28-135 IS USM lens, etc.). I noticed something that weirded me
out at first. The front end of the lens (the end where the lens cap
attaches) barrel wobbles around a little bit. The lens doesn't wobble in
the mount, just at the part that slides in and out as you zoom. Called
the dealer I got it from and they tried a couple of lenses and said the
ones they had did that. Figured I'd call Canon and they said the same
thing, that it was part of the design. Any ideas on this? Anyone else
notice it? I did this with the camera unpowered, as the battery charge
was too low and I had to pull it out to charge it.
Or am I making much ado about nothing?
Thanks much.

Yep, they all do it! Had my local store get a second one in, just to
check. And half a dozen responses here said the same.

Kinda counter-intuitive if you think of this as a precision piece of
optics. But its movement is lateral - not axial and not twisting, so I
guess this movement is built into the calculations. You're not touching
it when taking pictures, so it probably floats in the right position
when it's critical.

Mine has a bit of play as well. Haven't found it to be a problem.

Thanks for the reply. Glad to hear I'm not alone on this. I'm surprised
in all the research I did prior to getting this camera that no one has
mentioned it. I'm guessing that it's part of the stabilization process.

Mine too, but I have only taken 5 or 6 thousand shots through that lens
without a problem, so what do I know?

I vote for this being classified as a non-issue.

Welcome to plastic fantastic! I have experience with Canon, Nikon, Pentax
and several third party zooms made from plastics and there is always play in
the front end. Some models worse than others and the cheapest Nikon and
Canon zooms are pretty bad.

That's typical, all my AF Canon lenses did that, the 28-105 was the
worst. It was damn near a shift lens.

It is not mentioned due to it being irrelevant.
You will suffer no ill effects.

After about 20,000 shots though mine (literally), I'd call it a non-issue
too.

Where is this lens manufactured?
