70-200 f/2.8L IS II w/ 1.4/2x extenders?

Does anyone have any experience/samples with this lens combination? Whats the good/bad about this combo? What do you shoot with it? How is the AF speed, and how well does it work with AI Servo tracking? Do you have to adjust MA for autofocus when using the extender?

Im using a 5DIII and probably wont go to f/8, so Im not too worried about AF at f/8 with the 2x extender (even though there is a firmwareupdate on the horizon to fix this).

Thanks.

I have the 70-200 II and the 1.4x. Here's a sample. See more in my 1.4x Flickr set (some taken with the 70-200 and some with the 400mm f/5.6). I find it a great combo. IQ and focus speed hits are very minimal.

As I have read is that you don't loose much with the 1.4 in IQ and AF. But with the 2x the IQ will suffer a little and the af will be slower. Not sure what you mean by go at F8, but with the 2x your lens will be an 140-400 F5.6 so you dont loose AF.

Try searching the forum, there are dozens of posts about this topics with tons of example pics

Well I was just anticipating all the posts saying "you cant autofocus at f/8" etc. Thanks for the response though.

I tried searching before posting. Maybe I didnt search right then. Apologies.

*EDIT*

Just searched again. I assume I misspelled something because I found the more than dozens of threads about this very topic.

If you had the 70-200 F4 with 2x extender then you would have lost af, 140-400 F8. I think the 1D can af though.

Right, but I would probably shoot wide open (f/5.6 after extended) or stopped down (f/7.1). I would probably go to f/8, but only after Canon fixes the AF at f/8 issue in their upcoming firmware fix.

Youre right, the 1-series can handle the AF at f/8 with extenders.

The camera will autofocus when you have a lens/extender with a maximum apature of f/5.6.

It dosen't matter if you have your camera set at f/8 or smaller for the shot.

I didnt realize this. Thank you for clearing this up.

Im buying an extender now.
