Overview: Lens Control History, Use, and Integrations
Focus controllers are essential tools for professional cinematographers and camera assistants, enabling precise control over lens focus, iris, and zoom. These systems come in wireless and hybrid (wired/wireless) configurations, catering to different production needs.
Lens control devices are one of many tools in a filmmakers arsenal to capture a high quality moving image, enabling the camera team to spread out and focus in on different elements of camera and lens operation.

Lens Control History
Preston revolutionized the film industry with the introduction of the FI+Z (Focus, Iris, Zoom) system, setting a new standard for wireless lens control. At a time when focus pulling was entirely manual and limited by physical proximity, Preston’s precision-engineered, long-range wireless system gave camera assistants an unprecedented level of control and accuracy. This innovation not only streamlined complex camera moves but also became the gold standard for high-end cinematography, trusted on feature films, commercials, and live productions worldwide.
Focus controllers are now used all over the globe, on set and on location. They are powerful systems, and we’ve always wished we could use them during prep. Until then…
