Having just bought a 70 - 200mm F2.8 MKIII IS lens, for my EOS 5D MKII, I wondered about getting an extender the 2x MKII.
Has anyone any experience with extenders with this set up?
I had wanted the MKII, saved the cash then Boom - unfortunately Canon stopped supplying it, everyone did, so I had to get the even more expensive MKIII version, nice though, not used it in anger so far.
I do realise that although it will become 140 - 400mm, I will then have at best max f5.6 to play with. I also have heard that auto focus is sometimes a bit questionable with an extender. Not sure about IS either.
It would likely be used with at least a monopod if I did take a punt.
Thoughts and tips gratefully read. Thanks.
