So I just came back from a "Long Lens Demo Day" here in Stockholm.
Tried the following Canon lenses on A7RII and A6300 with the MC-11 (latest FW):
200-400/TC
400/2.8 II
500/4 II
800/5.7
300/4
400/5.6
100-400 II
70-300 (nano usm)
To be honest, I would never use this professionally. It just isn't reliable. Not just talking focus accuracy but the simple adapter is glitchy: stops focusing, freezes the camera, hangs up, etc.
When it works, it can work great on moving things (if they are big things, like a boat or an airplane, which there were plenty off passing by) or for shooting portraits.
But for BIF, it was almost missing impossible. Sometimes it would lock in but most of the time it didn't. It would do better with the 400/2.8 than any other, WO.
After this, I am actually returning my MC-11 since it hasn't been a month yet. I wanted to keep it for the TS-E lenses but it drains a ridiculous amount of battery (even though those lenses are totally manual focus and with no IS). Today with the big guns, it drained a full battery in about 30 min, which I never thought would be possible.
My advice, save some money for the GM100-400 or the for sure to soon be released 300/2.8 or 500/4 in E-mount.
I'm really interested in seeing how the A9 will change this, especially when Sony is claiming that the A9 will focus quicker and better Canon glass than a Canon body. I took some shots with the Canon 1Dx that was there for use and it was just dead on, even on the smallest BIF.
Just my opinion though. I do not shoot BIF. I just went out of curiosity.
I'll have a look at the shots I got later today and can upload them on Dropbox for sharing.

Thanks Nuno. I pretty much agree, reliability of focus at longer focal lengths is the problem. Below about 300mm, the MC-11 works much better. My testing of a variety of Canon lenses from 16-35mm to 70-200 F4 and F2.8 versions all worked very well for me. AF was spot on, unless the light was really crappy. The Sigma lenses I have work about as well as my Canon glass. I plan to buy more Sigma glass as they are superb optics, so a huge advantage for me is having image stabilization where none existed before.
I'm keeping the MC-11 to use with my shorter focal length Canon lenses (<200mm) and will continue to use my Canon gear for wildlife and BIF work. BTW, I really like the Sony A7Rii. Look for some Fuji X-T2 gear to show up on the B&S forum soon. I like the Fuji, but I can't justify keeping two sets of lenses.
