Use the Nucleus-Nano Wireless Focus Control System from Tilta to wirelessly control the focus of most DSLR, mirrorless, or cine-style lenses. The core of the system is the pairing of the focus control motor and the focus handwheel. 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 handwheel 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 handwheel features an attractive, comfortable rosewood grip.

[For custom stops or lenses without hard stop]
