A fairly comprehensive look at the Bartech Wireless Follow Focus System from Magnanimous Media.

Bartech Wireless Follow Focus

The BFD exceeds the performance of the old standards (Seitz, WRC-4) at a fraction of the price. Its compatibility with existing motors (Heden, ZB/SLD, FMG-6) allows the use of readily available used equipment as well as the new M-One motor. Its modular approach and interchangeable components allow you to start simple and build your way up to a full featured system, while providing back-ups in case of equipment failure.
