<p>Hello. I have just encountered the same problem by the sounds of the lines above. my lens when attached to my 7D continually tries to hold focus when in AV or Tv mode? even though the screen indications show the subject is focused? I have also had the error code ERR01 pop up and prevent use of the lens in the two modes mentioned above. This has now gone but the camera continually tries to focus - the lens ticks away like its possessed! has anyone else got this problem and is it likely to be the ribbon cable?</p>
