Speaking of the new Canon 70-200 (what perfect segue!) ...

->> Does anyone out there know what causes the front barrel/element on the current Canon 70-200L (IS) to become loose over time?

Like four months ago I sent mine in to Canon to get tightened up and such. I'd put up with the loose barrel long enough, and when the image quality started to suffer, I sent it in to the doc.

It's already come loose again. And I've heard this same thing over and over from other folks.

So I wonder, is there anything I might be doing (or don't do) that contributes to this? I take really good care of my equipment, so I'd be surprised. But still, I'm left to wonder.

Any info is much appreciated. Oh, and for what it's worth, I DO NOT want to turn this into a Canon bashing, Canon v. Nikon, etc. thread. If you have the urge to do that, go fly a kite.

Thanks in advance, and sorry to bother everybody with this. As the pirate with the steering wheel on his crotch once said, "Arrrgh -- it's driving me nuts!"

It only takes a minute to tighten the screws, but I'm not sure if it is the same fix with the IS version.
Cheers!

->> gerry, instead of sending the lens to canon try and find a reputable camera repair shop that can take apart the lens. most of the time they will drop a small amount of nail polish on the tops of the screws after they tighten them. this will kep them tight for a much longer time. I've had my 70-200 for almost four years and our local guy tightened it a couple years ago and put some clear nail varnish on the heads and it's still solid (and this comes after a really tough (on a lens) trip in afghanistan where the lens was assaulted with lots of vibration.

->> do you use the lens hood?
i used to have that problem. i believe it was because it would knock against my side. i rarely use the hood now and haven't had that issue in years.

->> Mine got to the point where I had to tighten it twice a week. I ended up putting some blue Loctite on the threads, that held it for several months.

->> I just fixed my IS version and looked at a non IS and it appears the same. Peal back the focus ring rubber a bit (Very easy, its not glued down) from the top and there is a hole rotate the ring until a screw appears in the hole and tighten it, there was 3 or 4 of them.

->> Hey guys:

Thanks for the notes. Unfortunately, it's pretty loose; and it sounds like something is rattling around in there now ... probably no bueno.

I'm throwing in the towel and sending it off to the doctor.

Matt -- I use one of those short rubber lens hoods, like the kind the NBA prefers. It's actually rolled up all the time. Good thought though, amigo. All's well up in NE? Hopin' so.

Thanks again fellers.
