Nima,
The MC-11 is fast and accurate with the 200/1.8. Lovely set-up (heavy too
I'm sure Metabones will be just as good.
I am more than happy to test it for him if he loans it to me for a week
Updates.
I just bought MB mark 5 with FW0.57. Tested with my lenses and result as below.
Sigma 85mm 1.4 ART.
Does not perform well. Always hunting. 7/10 chance of hunting. Wonder if this lens able work well with MC-11? How fast is the focusing speed? Did email to Metabones support team. No feedback yet.
Sigma 50mm 1.4 ART.
Performed well. Immediate focusing speed.
I had the same dilemma in choosing which lenses to adapt, so I tested the MC-11 and Metabones V, both with the latest firmware, at a store recently with the following lenses:
Canon 50mm f/1.2L, Canon 70-200mm f/2.8L IS II, Canon 85mm f/1.2L II, Sigma ART 50mm f/1.4, Sigma ART 85mm f/1.4
I also tested Sony's native 55mm f/1.8 and 85mm f/1.8, for comparison versus the adapted glass.
The Metabones V performed better on all lenses except for the 70-200mm f/2.8 IS II, where the MC-11 was more consistent in locking on to focus. The Sigma 85mm ART was definitely faster to focus on my A7II with the Metabones than the MC-11, not by much, but it was faster and confirmed by the store rep too (who presently only sells the MC-11). Perhaps you may have different results with a different camera model, but for me the Metabones V was an easy choice to make.
After my test, I purchased a used Canon 200mm f/2.8L II to try out and it works extremely well on the Metabones V and also does Eye-AF okay too.
This mean there is no issue with your camera A7II with 85mm 1.4 art.
Until now metabones support team has no feedback yet. So I cant not do anything since there is a latest firmware updated in my MB5. Hopefully the next firmware able to solve this issue.
My experience with the Metabones V and Sigma ART 85mm 1.4 has been exceptional. In some ways, it performs better than the native FE 85mm 1.8. Even in "Advanced" mode it was focusing more consistently than the FE 85mm while using in less well lit scenarios. Though I will say I wasn't overly impressed with either of the adapters on the Canon 70-200mm f/2.8L IS II. Perhaps my opinion would be different if I had the A7RII and not my lowly A7II.
I am a little surprised that there aren't more direct comparisons between the two adapters using the most popular and highly regarded Canon mount glass. I'm blown away how well my Sigma 85mm ART and Canon 200MM II are working with the Metabones V. I'm now considering getting rid of my Sony FE 35mm f/1.4 and going to Canon's 35mm f/1.4L II, and possibly swapping out the Sigma 85mm ART for the upcoming Canon 85mm f/1.4L IS.
Another benefit I saw in the Metabones adapter was the tripod mount that can be removed as needed. The Sigma 85mm ART is an absolute beast, and I haven't seen a working tripod collar/mount for it, so I'm no longer concerned about straining the mount on my camera body (if I were to have opted for the MC-11).
dannyer, which mode are you using your Sigma 85mm ART in on the Metabones? I've had good results with both Advanced and Green modes, depending on the circumstances. For general shooting I prefer Green mode with AF-C and Small to Medium Flexible focus area. Perhaps you could re-try downloading the latest firmware to see if that helps at all? Just my suggestion, from someone with very little experience using adapted Canon mount glass on their Metabones V.
If TechArtPro can solve the Eye-AF and enable older MF lenses to AF, it sure would be nice if Sigma can do the same with their MC-11 with a firmware update.

Sigma has enabled Eye-AF using the MC-11 even before the firmware upgrade of the A9 but somehow the effective area is limited to the center part in the horizontal position. The effective area is larger in the vertical direction. And yes, Sigma needs to work on updating the FW of the MC-11 and I know they will but they are taking their time apparently.
This is probably a long shot but is anyone using the Canon 500 f/4.5 or 500 f/4? I am looking into doing more BIF this winter than in years past and would be interested in either of these lenses.
The 500 f/4.5 in particular with the MC-11 would be attractive because of low weight and IBIS if this combo works.

what's your experience like with that adapter and the 200 1.8, Fred? I'm thinking of going to a Sony system very soon and that's one of my favourite lenses to use. Thanks!
My 200L works very well with MC-11. Adding IBIS to an already special lens makes it very, very awesome!
FWIW I've had best results with flexible spot wide. The lens isn't razor sharp at f/1.8 on the a7r2 the same way that the modern ones are but still pleeeeenty of resolution and it's unbelievably smooth rendering elsewhere makes it a great combo.

Can second all of this, have the same combo in use.
Has anyone tried the 14mm sigma 1.8 with the mc-11? More for the weight of the lens on the mount than the af performance. I'd be keen to get this with the new Sony a7r 3 but don't want to be putting strain on the camera itself. It doesn't look like the adapter has a foot mount??
I am getting really good results when the focus point is in the center but when I move it off center all my canon lenses hunt. Is this normal for this adapter?
That was my experience. However, I will say that both adapters allowed me to acquire focus with the Sigma 85mm ART f/1.4 faster than the native Sony FE 85mm f/1.8 in poor lighting. I did a small product shoot yesterday for a friend's e-commerce site with the adapted Sigma glass (and off-camera flashes) and was seriously impressed how well the Sigma lens focused in the dark scene before I had the exposure/lighting dialed in. I'd be willing to bet the farm that neither the native 85mm f/1.4 GM or 85mm f/1.8 FE could have focused in those same conditions half as fast, or possibly at all. As much as I hate to lug around a cumbersome lens like the Sigma 85mm, it's autofocus capabilities are worth the heft to me. I'd much rather adapt this lens using the Metabones V, or even Sigma MC-11, than use either of the native options at this point in time.
