Re: Which lens is sharper with TC-20E III: 70-200mm f/2.8 VRII or 70-200mm f/4 on D800/E

I have done some searching for an answer to a question that I have but cannot seem to find my answer.....hence the reason for my post.  I have read many posts about the Nikon teleconverters with the 70-200 vrii 2.8 which I happen to have.  I know that the autofocus works at the f5.6 aperature which is where I would be at with a 2x but what I would like to know is if you stop the lens down to f8 to more, will the autofocus continue to work assuming I am in good daylight conditions?

Thanks in advance.
