Operator Control Unit OCU-1

 

 

Introduction

The new ARRI Operator Control Unit OCU-1 is an addition to the WCU-4 lens control system, and enables operators to override and return focus, iris or zoom controls at the touch of a button.

This device gives camera operators full control of their lenses when they want it. The OCU-1 will help to save precious time while framing shots, as the camera operator will always have the ability to control the lens, even when motors are attached. With its override function the OCU-1 offers camera operators the possibility for adjustments when focus is slightly off and gives the focus puller an override indication on the WCU-4.

The OCU-1 is a simple, low-cost derivate of the Master Grip Wheel in a very convenient form factor. Hence the Override function will be available for the Master Grips as well.

The device enables control of EF lenses mounted on ALEXA Mini and AMIRA cameras without any additional external motors.

Fitting into a long ARRI tradition of innovation, the OCU-1 will improve on-set efficiency and control. It is small, lightweight, and easy to use, has the same control wheel, display and LBUS integration as the ARRI Master Grips, and with its flexible mounting options it can be easily mounted onto common 15mm or 19mm rods, ARRI Rosette, or 3/8” mounts. The wheel can also be used to control the roll axis of the ARRI Stabilized Remote Head SRH-3.
