The core of the system is the pairing of the focus control motor and the focus hand wheel. The units can connect to each other from 300′ away, and can be mounted in a variety of ways.

The units support run/stop functions and setting hard A and B limits for more control over your camera and lens. The hand wheel is powered by a single 14500 lithium battery and the motor is powered by your camera or a battery via its micro-USB connector. The units are both constructed of durable materials, and the hand wheel features an attractive, comfortable rosewood grip.
