Oct 05, 2009 08:10 | #2 PipesInTune wrote in post #8763133  I'm wondering if anybody has experienced this problem... Canon 28-135 IS lens focuses intermittently. It's just this lens, so I know it's not the camera body. If I re-mount the lens, turn camera on/off, etc., I can get it to work. Contacts are clean. Can't figure out why? did you mean, the focusing hunts or AF does not work at all? Jerome

jblaschke Goldmember  More info | My 28-135 has never had a focusing problem, but I had to send it in to Canon because the IS started working erratically, switching on and off rapidly. The lens wasn't under warranty, but Canon fixed it for free. Wonders never cease.
