Take Instant Control at Critical Moments on Set

The ARRI Operator Control Unit OCU-1 is a revolutionary, compact control system that solves a classic filmmaking dilemma: the struggle for focus between the camera operator and the 1st AC. Designed to mount directly onto the camera rig, gimbal, or pan bar, the OCU-1 enables operators to quickly override and reclaim control of any assigned lens function (focus, iris, or zoom) from wireless hand units like the ARRI Hi-5 or WCU-4. This on-the-fly override capability saves precious time during setup, framing adjustments, and fast-paced rehearsals.

Streamlined Rehearsals and Smooth Focus Handback

The true power of the OCU-1 lies in its seamless, non-disruptive workflow integration. During critical setups, an operator or cinematographer can touch a single button to focus on a subject or demonstrate a frame to the director without waiting for the focus puller. Once the shot is locked or the rehearsal is complete, control is instantly returned to the 1st AC's remote handset without any physical jumps, system recalibrations, or menu lag.

Compact, Rugged, and Highly Configurable

Despite its incredibly small and lightweight footprint, the OCU-1 is built to ARRI’s legendary standards of set durability. It features an intuitive, smooth control wheel and three customizable user buttons that allow operators to mold the device to their exact shooting style. Whether you are shooting with cine lenses and cforce motors, executing smooth gimbal tracking shots, or controlling internal electronics on motorless EF lenses, the OCU-1 serves as an indispensable on-board tool that deserves a permanent spot on every camera package list.
