ARRI OCU-1: a mini Master Grip for €1,170 – IBC 2018

At IBC in Amsterdam ARRI announced the OCU-1 (Operator Control Unit). The OCU-1 was primarily designed to enable camera operators to override and return focus, iris, and zoom controls from the Wireless Compact Unit WCU-4. However, it can also be used as an electronic follow focus by solo shooters, as a lower cost option to going with a full ARRI Master Grip setup.

The OCU-1 is small, lightweight, and easy to use, and it has the same control wheel, display and LBUS integration as the ARRI Master Grips. If you are using Canon EF lenses with an Amira or Alexa Mini, the OCU-1 gives you full control of iris and focus without having to use any external motors.

If you are using PL mount lenses you can add CForce Mini motors that can be controlled directly from the OCU-1. The OCU-1 has a range of mounting options and can be attached to 15mm or 19mm rods, an ARRI Rosette, or 3/8” mounts.

If you use the OCU-1 in addition to the WCU-4 lens control system it allows shooters to have full control of their lenses when they want it. The OCU-1 features a clever override function that enables you to override and return focus, iris, and zoom controls at the touch of a button. With its three assignable user buttons and a finger wheel, the camera operator will always have the ability to control the lens, even when motors are attached. This will help camera operators to save time while framing a shot or doing adjustments when the focus is slightly off. The OCU-1 override is indicated on the WCU-4 screen and enables the focus puller to re-engage control smoothly without a jumping motor.

The OCU-1 will work with other cameras from different manufacturers if you purchase a compatible interface box.

Stabilized Remote Head SRH-3 support
The wheel can also be used to control the roll axis of the ARRI Stabilized Remote Head SRH-3.
