    The Tilta Nucleus-M Wireless Lens Control System Partial Kit IV contains the essential elements for pulling focus and iris wirelessly. The kit includes the Nucleus-M FIZ hand unit controller, two Nucleus-M motors, two removable lens belts (DSLR Lens Follow Focus Adapters), two motor power cables, two marking disks for the hand unit, a lanyard for the hand unit, and a battery charger unit.

    This partial kit is a dual-axis system, typically controlling focus and iris. The system can wirelessly pull focus from up to 1000' away, and the batteries can power the hand unit for approximately 10 hours on a single charge (batteries not included). The first motor is powered via the included D-Tap to 7-pin cable; the second motor daisy-chains to the fist via the 7-pin to 7-pin cable for power. The lanyard attaches to the hand control unit, allowing you to wear it around your neck.


    • The motors feature cine standard 0.8 MOD 32 pitch drive gears. Each motor includes a 19mm rod clamp and a 15 to 19mm adapter bushing, allowing you to mount the motors onto either a 15mm or 19mm rod.
    • The motors power from a D-Tap connector, and then pass power by daisy-chaining via the 7-pin connectors with the included cables.
    • The FIZ hand controller and each handgrip power via two 18650 3000mAh, 3.7V Li-ion batteries.
    • The batteries in the FIZ hand controller will last for more than 10 hours, and up to 48 hours in each handgrip, when idle.
    • Please note that batteries are not included and must be sourced separately.
    • The system features three ranges: low, medium, and high. It supports up to 15 channels to select from, and the controllers pair with each motor via the motor ID.
    • The FIZ hand unit can control three channels (focus, zoom, and iris), as well as override the handgrips.
    • The motors can calibrate on lenses with or without hard stops, such as a photo lens with follow focus gears.
