Has anybody got any solutions for powering accessories like lens control and cinetape etc? also has anyone used this in a steadicam set up. As there is only hdsdi out one would need down converter to use wireless video.

I used wireless BarTech (BFD) WIRELESS REMOTE FOCUS on 15f Jimmy Jib crane, I had a separate battery for FF system, and it is a hassle to press record button, no remote jet.
