I bought a used Rebel EOS T3. It appears to work as the shutter and flash will move when I don't have a lens on it. When I bought the camera there was a Canon EFS 18-55mm lens in the box. I tried putting that on and am getting a Error 01 (clean the contancts) code on the camera. Both camera and lens contacts are perfectly clean. Am I getting this code because the lens is not compatible with the camera or is it more likely that the lens is broken?
