Overview

The Tilta Nucleus-M Wireless Lens Control Kit V (WLC-T03-K5) is a partial kit from Tilta's professional wireless FIZ (Focus, Iris, Zoom) system, providing filmmakers with precise, cable-free control over their lenses. The system centers on a compact hand unit that puts three-axis lens control into a single device — the main wheel handles focus, a secondary wheel controls iris (or can be reassigned as a zoom speed controller), and a toggle manages zoom. For productions that need to split duties, the Nucleus-M also supports two-handle operation, letting you divide control between operators for more complex shooting scenarios.

What sets the Nucleus-M apart at its price point is the thoughtful design of its control interface. The hand unit features an intuitive focus mark system with haptic feedback — as you turn the focus wheel, the unit vibrates when passing a preset mark, enabling precise focus pulls without ever looking down at the controller. Programmable hard stops let you define a specific focus range, so you can pull between two subjects with confidence. The motors are engineered to handle everything from lightweight DSLR lenses to heavy cinema zoom lenses, making the system adaptable across different camera packages. As a Kit V configuration, verify the included components against your needs, as additional motors or accessories may be required for a complete three-axis setup.
