I just purchased the Canon 100-400L IS ii and was wondering if my 2x ii teleconverter is compatiable with it? Will AF work? How does this combo match up? Thanks.
I purchased a 1.4 iii to go along with the 100-400 ii which i have heard works quite well on the 5D4 - Iit sounds like the 2x ii won;t work that great so I think I'll just sell it at this point. Thanks for your feedback.
