Canon AF problems with 300mm ll lens
Jan 15, 2013

I am fixing to take my lens in to Canon for the third time for focus problems. But I was wondering if any of you guys are having AF problems with the new 300mm II lens?

When it hits it is sharp now. But it rarely hits. My new 500 is spot on. But this 300 is a nightmare with my 7D.

Would appreciate some feed back if you have or have not had problems. With a T.C. is is a total mess. Unusable.
