DjMagra’s stuff ‘n’ stuff

Unfortunately, my EF-S 17 - 85mm is currently out of action. I’m not 100% sure what’s up to be honest. Barry first noticed a problem when he was using it here a few weeks back, it would appear that the aperture ring is locking up. He’s had the problem on his 30D, and I have the exact same problem on my 20D. I’ve tried cleaning the sensor connects on the lens (with a rubber tip on a pencil as suggested) and that’s made no difference.

I’m looking for a good, clueful camera shop in London to take it into. The lens will presumably go back to Canon for repair, but, it would be nice to build up a good relationship with a good camera store here in London anyways. I don’t really want to go via Jessops to get the lens returned, that’s like going to Tesco looking for a tailored suit!
