The Tilta Nucleus-M Wireless Lens Control System is designed with a maximum operating range of 1000 ft., and includes two lens drive motors with built-in receivers, as well as a FIZ hand controller, and two handgrips. The left handgrip is designed to control iris and zoom, while the left handgrip controls focusing control. Each lens drive motor features a cine-standard 0.8 MOD drive gear, as well as two 7-pin connectors, which allows you to swap or interchange each motor. The motors are powered by daisy-chaining via the 7-pin cables, & each motor includes a 19mm rod clamp (with 19-15mm adapter bushing).
