Trouble with 40D

First of all, greetings to my fellow Canon DSLR users.

My almost an year old 40D which has been mostly well behaved has acting cranky of late. About two days back, I started getting the infamous error 01, after cleaning the lens contact for about five times- everything seemed to be fine.

Sadly, the aperture of my camera appears to stuck into a very small hole now. It has focusing problems. Any help and information will be greatly appreciated.

Sound like a lens issue rather than a camera issue. Do you have another lens to put on it so you can test it out?

To establish if it's a camera or lens issue, do you experience the same problem with a different lens?

Afraid I don't have any other lens. However, this seems to be a lens issue. For reference, this one is an EFS 17-85mm IS.

Any suggestions on what I could try, apart from taking it to the service center?

For what it's worth, I had a similar problem with this lens. It had to go back to Canon for repair.

Take your camera to a local shop if you can. Try out a new lens on your body just to check. But it sounds like you need to call canon and get a repair quote. I dont know whether the repair costs merit repairing it or replacing it on that lens.

Ah, well then, guess I shall have to go get it checked.

Thank you, everyone.

Browsing around the net, a LOT of people seem to have the same issue with this lens.

Hi junior mamber, i just got the same problem on my 17-85mm EFS lens. did you send to Canon for repair? if yes. how much they charge for the repair and what actually cause this error 01?
