If it has a focus ring motor that’s controllable via the API, you could write your own autofocus algorithm.

Professional cameras often do not have auto focus, compare to some RED camera models. You either prepare your focus points ahead of time or you work in teams, where your camera assistants act as the "auto" focus.

That makes sense, I guess I missed that it's a cinecam not a still camera.
