Back to the power draw issue, I wasn't able to install the HotFix firmware for some reason (Chris said I might have to wait for an official release... engineering stuff), but... I was on a shoot today with an Arri Mini that had a WCU-4 and did Focus and Iris through the camera's wireless. All powered through the Movi Pro perfectly! Camera, Focus\Iris, Tomahawk. Camera was on the 6A D-Tap and Tomahawk was on the 2A D-Tap on the TSU. Without the Hotfix, Tomahawk is still not working on the GCU 2A D-Tap. The Focus and Iris were both working throughout the Movi's battery life -- from 100% all the way down. I can tell you, it was AWESOME only dealing with Movi Batteries and being able to hot swap. Also, it felt lighter not having to use V-mount batteries on the rig. And of course, the Movi Pro is such a dream to work with, fast to adjust, the new Mimic is amazing, and the Director and DP were both very happy. Anyway, just thought I'd report on this particular configuration, because I'm actually surprised the Focus and Iris motors don't drag the Arri over the 6A limit with everything going on.
