17-40 zoom noise - does yours sound like this?

Hello,

My 17-40 sounds weird when zooming normal and fast.

Does yours sound like this?

Thanks.

I really had to turn the volume up to hear your sound; mine is essentially noiseless but then I haven't payed close attention to what it sounds like. In your case it sounds like gears turning which is a little odd for an USM lens.

It is hard to tell from the recording how loud your lens is. My 17-40 makes a barely audible noise when zooming; if I put my ear close to the lens then I can hear a smooth swoosh with something that sounds like gear noise superimposed on top of it. It is not something I ever noticed with the lens on the camera. If yours is like that then I'd guess it's probably fine. How long have you owned it? If you've had it a while and it recently got a lot more noticeable, then it might be a good idea to get it checked out.
