Overview

The Tilta Nucleus-M Wireless Follow Focus Kit is built for the one- or two-person camera team that needs precise, repeatable lens control without the tether of a hard-link system. Whether you're flying a gimbal through a crowded venue, mounting a camera to a vehicle for a commercial shoot, or working a shoulder rig on a documentary, the Nucleus-M's 1,000-foot wireless range gives the focus puller — or the operator wearing both hats — genuine creative freedom. The three knob-rotation settings are a practical, underappreciated feature: dialing in 85° for a fast, punchy rack focus and switching to 310° for a slow, meditative pull to infinity is the kind of workflow flexibility that shows up on screen.

The motor's clamp-on rod design and standard 0.8 mod cinema gear mean it drops onto almost any existing rig without sourcing adapters or modifying your setup. Power management is equally thoughtful — a single P-tap input to the first motor, daisy-chained to additional units, keeps cable clutter off a rig that's already carrying a camera, monitor, and battery. The ARRI rosette on the handgrip plays nicely with established shoulder and cage ecosystems. This Kit 2 configuration (one motor, one right handgrip) is the logical entry point for operators who want to evaluate the system before committing to a full FIZ build, and the modular architecture means adding motors or a left handgrip later is straightforward.

Key Features

Handgrip features include three knob-rotation settings, optional adapters for either bar- or ring-based gimbals, LED indicators, and an LCD display. With a wireless control range of up to 1000', the Wireless Handgrip can be used for drone or car-mounted shots in addition to handheld configurations.

Customizable focus, iris, and zoom control Run/stop control for select cameras ARRI-style rosette mounting and optional gimbal adapter mounts 1000' wireless control range 85, 180, and 310° knob rotation settings LCD display and LED indicators

To power the motors, only one power port on your camera rig needs to be used. Simply plug the P-tap power cable into one of the motors and then daisy chain power to the rest of the motors with the short 7-pin to 7-pin cables. The motors can be powered through a power source that has a voltage output ranging from 7.2V-24V.

Motors fit standard 15mm and 19mm Rods . Ideal for Gimbal, Drone, and Shoulder-mounted setups.The motors are designed to clamp onto 19mm or 15mm rods (with the included rod bushings). This clamp-on design allows you to easily attach and detach the motors without needing to remove any other accessory from your setup. Every motor has a 0.8 mod, 35 tooth, 32 pitch gear attached, which is the standard gear size for cinema lenses. The torque of the Nucleus-M Motor at 14.8V is 2.5N·m

Function as a one-person camera team & keep the form factor of your camera setup to a minimumThe motors allow for automatic calibration of the lens as well as manual calibration if you are using lenses that don’t have hard end stops at close focus and infinity.

Frequently Asked Questions

The motor ships with a 0.8 mod, 35 tooth, 32 pitch gear — the industry standard for cinema lenses — so it will mate directly with virtually all professional cinema glass without an adapter ring.
The right handgrip offers three selectable knob rotation settings — 85°, 180°, and 310°. Use 85° for fast rack-focus pulls in run-and-gun or event work, and 310° for precise, gradual focus transitions on longer focal lengths or macro work.
Yes. The motors accept 7.2V–24V input via P-tap, so any standard V-mount or gold-mount battery with a P-tap output will power the system. Daisy-chain additional motors from the first using the included 7-pin cables to keep your cable run clean.
Tilta rates the handgrip at up to 1,000 feet of wireless range. In practice that covers most drone and vehicle-mounted scenarios with clear line-of-sight; dense urban environments or metal vehicle bodies will reduce effective range, so test your specific setup before a critical shoot.
Both. The motor will auto-calibrate lenses that have hard end stops at close focus and infinity. For vintage or modified glass without hard stops, manual calibration is available so you can define your own travel limits.
