Please clean the contacts on the lens and the camera.&nbsp; Only light pressure is required.&nbsp; Please take precautions to prevent any debris from entering the camera.</P><P>&nbsp;</P><P>If the issue persists, does this happen with all your Canon lenses?&nbsp; If not, which lenses are affected?</P> Tue, 20 Nov 2012 04:39:57 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/why-do-my-EOS-600D-stops-focusing-after-a-hundred-shots-And/m-p/3767#M3996 Richard 2012-11-20T04:39:57Z
