My EF 70-200mm f/4 goes quietly when IS switch is off but does make quiet a lot of noise and fails to lock on the object when IS is on. Does anyone have the same experience?

Wrong forum. Try the Canon SLR Lens forum.

Also, what kind of feedback are you expecting? Sounds abnormal to me. I would expect a lens to focus even if you have IS turned on. So, you may as well start getting it serviced.
