This wireless electronic follow focus was a great find at BIRTV. It was actually shown to me by Andrew Chan of SLR Magic. I was really impressed by it's light weight, size and responsiveness for the controller. I had to go see at the booth. The units model number is PDL-AF and is called the Live Air. The company, PDMovie has a more expensive, bigger unit called the Remote Air 4 as well.

We have the Live Air to test in our labs and will be doing a review of it soon.

In real life - the smaller the crew - the more important is tight two rods connection and the better lens fixation is required.

@halfmac how does this compare to the Nano for single user use?seems its much cheaper now about same prince as Nano
