So I find myself running into these small mirrorless "cinema" cameras more and more as a c or d cam. Usually the need is only really to be able to run it in some set location, with preset focus and settings. But! There is always the want for RS capabilities so they don't have to run non stop. Now I've seen the consumer grade LCS's have run stop abilities on these cameras, but does there exist a micro usb to RS port cable of some sort that will make it play with Arri/Cmotion/Preston motors and controllers?
