Evening all 
I've been happily using my 17-85 USM lens for a while, and today I got a few Err01 (clean lens contacts, which I did and it didn't help) messages while using it in the studio. Just before I'd noticed some harsh overexposure on a couple of images, and when I pressed the shutter the viewfinder flickered before the error message appeared.
Put my 28-105 on the camera and everything's working fine with that, so it's definitely the other lens.
Is this a common problem?
