Tilta Nucleus-M Wireless Lens Control System

The Tilta Nucleus-M Wireless Lens Control System is a professional three-channel wireless FIZ system designed for precise control of focus, iris and zoom on cinema and photographic lenses. It can be operated from the dedicated FIZ hand unit or from the left and right wireless hand grips, which makes it suitable for traditional camera-assistant work as well as gimbals, shoulder rigs, vehicle rigs and other setups where direct access to the lens is limited. The system is modular, so control of individual lens axes can be assigned between the hand unit and the handles depending on the needs of the operator and focus puller.

Three-channel focus, iris and zoom control

The Nucleus-M is built around independent wireless control of focus, iris and zoom. The FIZ hand unit combines a large focus wheel with dedicated iris and zoom controls, while the two wireless handles allow lens functions to be operated directly from a gimbal or shoulder-mounted camera rig. This makes it possible to divide responsibilities between operators or keep full lens control close to the camera when working as a solo operator.

Long-range 2.4 GHz wireless operation

The system operates in the 2.4 GHz band and offers a working range of up to approximately 1000 ft / 300 m for the FIZ hand unit under suitable conditions. The motors contain their own motor drivers and wireless receivers, so a separate external MDR does not need to be mounted on the camera. This reduces the number of components on the rig and allows the motors to communicate directly with the hand unit and wireless grips.

High-torque motors for cinema and photo lenses

Each Nucleus-M motor uses a standard 0.8 MOD cinema gear and produces up to 2.5 N·m of torque at 14.8 V. The motors can be mounted on 19 mm rods or on 15 mm rods using the appropriate bushings, making the system suitable for both full-size cinema builds and lighter camera rigs. Automatic calibration is available for lenses with hard end stops, while manual calibration can be used with photographic lenses or optics that do not have mechanical stops at minimum focus and infinity.

Daisy-chain power and remote camera control

The motors accept 7.2–24 V power and can be daisy-chained, allowing several motors to share a single power source from the camera rig. A compatible Nucleus-M Run/Stop cable can also be connected to an available 7-pin motor port to provide remote recording control from the hand unit or handles. This can be particularly useful on gimbals, cranes or car-mounted setups where the camera body is difficult to reach during a take.

18650-powered hand unit and grips

The FIZ hand unit and each wireless hand grip are powered by two rechargeable 18650 batteries. Tilta specifies up to approximately 10 hours of operation for the hand unit, while the hand grips can operate for up to two days depending on use and battery condition. The system therefore works well for long shooting days without requiring continuous external power for the controllers.
