ARRI OCU-1

The Operator Control Unit OCU-1 is an addition to the WCU-4 lens control system on ALEXA Mini and gives camera operators full control of their lenses when they want it. Fitting into a long ARRI tradition of innovation, the OCU-1 will improve on-set efficiency and control.
The OCU-1 enables operators 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 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 enables the control of EF lenses mounted on ALEXA Mini and AMIRA cameras without any additional external motors.
