Re: Canon f/2.8 300mm IS USM II - How to set to "0" again

Are you using IS? I wonder if the problem occurs with IS on or off, or in different modes. If the problem is there with IS off, then this can be ruled out.

Maybe a problem with the AF motor. Is this happening with action shots only, or static also? I'm trying to understand if the problem is AF speed (too slow for action shots) or lack of AF accuracy.

We have all read good & bad reports about Canon service centers. I wonder how thoroughly the tech tested your lens.
