From what I heard, it's still pretty rough but gets the job done. Lots of 3d printing and trying new hardware that's coming out in the filming circles (that I'm not part of, heh).
A lot of the equipment is 3d printed in house since most all of this tech is still so new. The directors really like manual focus for much of their work, so I'm pretty confident there's no auto-focus ability. Similar to when you add a conversion between manufacturers with rigs and lenses. Hoping we can post more soon on the fun stuff the team is creating!
