I picked up a sigma 18-35 as part of a package with an Eos 5 I bought today. I get an err01 on my 50d if I fire a shot at anything other than wide open. I know the answer is probably no but is there anyway to fix this cheaply or myself. I've tried using the Depth of field preview button and giving the lens a shake/tap figuriing it might free them up but nothing.
Aperture will not stop down on old sigma lens

It would need re-chipping to work with modern bodies, unfortunately I don't think Sigma offer the service anymore.
Edit, definitely no more re-chipping. A discussion on AP:

Dave is right.
Old Sigma lenses rarely work on new EOS bodies. They started having this issue in 2002 when EOS underwent some subtle changes at the same time Canon moved from ATTL to ETTL flash control.
