I have a new Canon EOS Kiss camera and a friend of mine has a Sigma Aspherical IF 28-200mm lens she used on an old Canon EOS film camera (old as in 10 years or so). I tried using the lens on my camera. The auto focus worked fine but when I tried to take a picture the camera froze with the following error:
Communications between the camera and lens is faulty.
Clean the lens contacts.
I don't think my contacts need cleaning because the camera works fine with a 18-55mm lens.
How can I solve this issue?
