Sigma 17-35 HSM EX: No Auto focus on 10D

MesaMan

Alright everyone, just got some new glass - Sigma 17-35mm f2.8-4 HSM EX.
Get it on my 10D, and the auto focus doesn't work.

I was wondering if this is a problem for other 10D/Canon users? What can I do about it?

I hear that you can change/upgrade :scratch the "chip" in the lenses. If true is this expensive?

So many questions, I hope someone can help me.
Many thanks,

Does the auto focus work at all? I had a similar problem... see this thread:

Hi Jim,

Thanks for your reply, before posting this topic I ran a search and found that thread. It is NOT this problem - the AF does not work at any aperture and is not turning the ring at all.

The lens looks like it could be a good 'un apart from no AF.... GGrr

Did you buy it new or used? How old is this lens? Looks like this lens should be compatible. Is this the lens?

Hi Jim, It's secondhand and the same as the one pictured although it's not the DG and it's the larger 82mm filter version. I believe this to be older?
