20D 17-55/2.8IS and Err 00 and Err 99
Yes I fixed it twice already. Replaced IS unit once. I am thinking its just not durable for how I use it. May be move up to 5D and get all L set like 24-70/2.8L and 70-200/2.8L IS and 16-35/2.8II. If so I will wait til spring.
I will bring it into canon on Monday when I am back from China.
