If you are using a filter, take it out. This lens AF simply cant work properly with one.

I'm curious - what leads you to say that? Are there any documented tests on that?

Google is your friend.

I experienced it myself with hoya protector.

The lens front focus over 400mm 90% of the time.

Took it out "et voila".
