So, below I had a review of the Jag35 Wireless Follow Focus version one. This video shows version 2, which is yet to ship according to the Jag35 site. This is less of a review and more of a preliminary look.
Quick pros? Seems to be powered by Canon SLR batteries, which matches its target market. Price.
Quick cons? Seems loud, but hard to tell in this video. The motor in this video looks pretty wide, so it might be hard to get other things in beside it on a lens, or use it with short lenses. The controller has sliders on the front, which would get bumped easily by anyone turning the wheel.
