So 400 works well even with TC and adapter? That's impressive. Even tracking is good? In what mode do you run it? Wide with AF lock on for stuff like this?

As a part of the lens evaluation process for a wildlife trip to Costa Rica in 6 weeks - the lens used is Canon 400mm DO Mark II with a 1.4X TC via Metabones IV. The continuous AF is pretty responsive and it didn't have any issues following the target.
The chimps at the LA zoo put up a great show that day. There are several young chimps in the clan and they know how to make people laugh. Yes, it does and quite well actually. Even tracking is not bad. The only drawback is the lack of a few AF features offered by a native lens. Of course, at this focal length, I am not worried about Eye AF but the Lock-on AF (with Selectable and Expandable AF points) would be actually very useful in this case. But it is what it is.
Has anyone tried the new Sigma MC-11 adapter? From description seems it has all features offered by a native lens.
