Autofocus on my Canon 28-135mm f/3.5-5.6 EF IS fails


Hello. First, check the contacts on the lens mount--you're looking for bent pins, oxidized(odd-colored) metal, damaged contact points, etc. The camera must communicate reliably with the internal circuitry of the lens unit. If there is any dirt, moisture, intermittent contact going on, the sensitive focusing electronics will be effectively blinded. If all is fine with the contacts, then the problem lies with the circuits in the lens that provide critical focusing data to the camera. Movement of certain parts causes electrical changes to occur at a calibrated rate--if the camera loses connection, it can't tell if the lens is actually adjusting. You'll have to send the lens in for repair--http://www.usa.canon.com/consumer/controller?act=SupportIndexAct. This address should get you started.--Hope I helped!---Rick

If the AF motor is still alive + spinning, this should be fixable without any replacement parts.

My Canon 40D can't handle bright yellow and reds. It blurs the detail and overly saturates the subject (flower close-ups) - so that the bright red poppy is overly saturated and lacks detail even though...
