Hello, I get this error message on my new Canon EOS 600D:
ERR 01 Communication between the camera and lens is faulty.
Clean the lens contacts.
Do you have an idea what is wrong? Cleaning the contacts did not help. I tried to clean the contacts but time to time I receive this error message. I use original Canon EFS 17-55mm / 2.8 lens.
This is an excerpt from Canon EOS manual:
-Clean the electrical contacts on the camera and lens.
-Use a Canon lens.
-If the instructions above do not solve the problem, please contact your nearest Canon Service Center.
Do you have this problem with another lens? Or did you try to attach the lens to another camera?
