If you're wondering if the above video is legit, it sure seems like it. The manufacturer is found at this website at https://www.plcelectronicsolutions.com. If you're thinking about getting something like this, get ready to dish out over $1500.00 for just the Receiver. Which means you still need the lens gears, the motor, and of course iPhone not included. I think everyone might be better off going with the the new RedRock Wireless Follow Focus seen at NAB.
