A separate iris control unit 

The Single Axis Unit SXU-1 is a simple, single-channel hand unit that can be set up to control focus, iris or zoom. The SXU-1 can be used alongside the WCU-4 for separate iris control, operated by the DIT or cinematographer in situations where subtle exposure adjustments are required during travelling shots.

Operator Control Unit OCU-1 Extended Set

Master Grips

K2.0009363, K2.0009490, K2.0009493, K2.0009494

Solid, ergonomic camera handgrips with assignable user buttons and control rocker for super-smooth zooming. Includes steel ARRI rosette and LBUS interfaces.



Combining the compact size and low weight of the popular ALEXA Mini with the large-format ALEXA LF sensor, ALEXA Mini LF brings exciting new creative possibilities to ARRI’s large-format camera system.



Compact, lightweight, and self-contained - ARRI ALEXA Mini is the small and versatile allrounder in the ARRI camera family.

Alexa LF


ARRI's new large-format camera system consists of the ALEXA LF camera, ARRI Signature Prime lenses, LPL lens mount and PL-to-LPL Adapter. Featuring a sensor slightly larger than full frame, the ALEXA LF camera records native 4.5K with ARRI’s best overall image quality.



It has a built-in video transmitter which makes the camera smaller and lighter than it would be with an external transmitter. It also means fewer cables around the camera and fewer associated problems, since cable failure is by far the most common technical hitch on set. Camera setup and power-up are quicker, and productions are able to move faster.
