Are there any canon ef/ef-s adapters for sony e-mount cameras that support continuous AF?

Specifically are there any mount adapters for the sony fs700 that support continuous autofocus with canon ef and ef-s lenses? There are quite a few that support autofocus in photo mode, but none seem to support continuous AF in video mode.

I think the only large-sensor video cameras that support a usable continuous AF are the Canon cameras with their dual-pixel AF technology. The new Canon C300 Mk2 looks like it's the absolute state-of-the-art for continuous AF at the moment, and I don't think it's going to be challenged until somebody comes up with equivalent tech. ( which will probably take a few years )

Thanks. I was actually looking at the c100 w/ dual-pixel AF as well but the lack of 4k and slow motion was a deal breaker for me. Although I really like the colors.

The fs700 does have continuous AF in video as well (don't know which AF is better but would rather have it than not), but supposedly only for sony lenses. I'm guessing it's not possible to fool the camera into thinking it's working with a canon lens?

...But I haven't seen anything that works as well as the Canon dual-pixel technology, it seems to lock on and work almost instantly as long as your subject is in the focus area.

The face-tracking feature of the C100 Mk2 and C300 Mk2 also looks really good, as I find it a pain to keep focus during tightly framed interviews with a person that is constantly moving backwards and forwards as you shoot. This Canon dual-pixel tech seems to handle this problem with ease.
