I have a Canon Efs 17- 85 stabiliser ultrasonic lens. Recently I start to have problems with the autofocus. When you focus on somthing you can hear the lens motor trying to focus. You can see the focus point and the autofocus keep on searching the focus.
What can be the problem and how can it be fixed. I need help please.
I had a similar problem with the 17 to 85mm. A trip to the Canon repair facility solved the problem. I believe it was the ribbon cable. My lens would continuously hunt when zoomed long. I do not remember what the repair cost was. If I had it to do over, I would park the money in another lens...I have not used the 17 to 85mm since getting it repaired. It will only work with older bodies.
