It will not autofocus. I can take a picture in MF vs AF but in AF it wont let me zoom and trys to focus over and over. Issue is it worked one day and then the next would not. I have another lens a 55-250mm that works so I dont think it is the camera.. The original 2009 EF-S 18-135mm f/3.5-5.6 IS had a micro-motor autofocusing mechanism. AF should always be disengaged before attempting to manually focus any micro-motor lens. Not disengaging autofocus by sliding the AF/MF switch to MF (manual focus) before turning the manual focus ring can damage the lens focusing mechanism. My canon 18-55mm IS II lens has recently stopped working after a month. Focus ring will still move in auto but doesnt get close to the image being in focus. When the lens is in manual moving the focus ring does almost nothing at all. If the object is maybe 4 inches away the camera is able to focus onto it but anything further causes problems. "The camera is 3 years old I use the camera 5 days a week, and on average, I take about 800 pictures. in just one day" You are one lucky fellow! That is well over half a million shots for a camera that has a life span estimated at 75,000. I'd say it it time to retire that work horse and And the best buy in all of Canon lenses is the EF 24-105mm f4 IS USM. You can find this lens in what is called a "white box". Sometimes in the $700-$800 area. It is a brand new, with full warranty, lens from a Canon kit. They are also easy to find in great shape used. Yes, all these sugestions are more expensive that a 18-55mm but there is That is exactly right. My brother gave a replacement lens. Perhaps I can scavenge a part off of it. I would just use his but it's not an ultrasonic lens. I experienced the same problem with the AF not working. I tried the careful fixes like cleaning and the multiple steps Julius suggested. None worked, so I decided to try Crystal's "pop" method. It worked! What did I have to lose? I did lose a day at Mackinaw, but making up for it today! mWMQ3.
