Lens Control SystemsARRI WCU-4 Lens Control System

Integrated Wireless Lens Control System for Alexa Plus.

£350 Per Day / £1050 Per Week

Three Axes - All Inclusive
The Wireless Compact Unit WCU-4 combines three axis of lens control with a lens data display in a compact and ergonomic housing. Weighing around 780 grams including battery, it’s one of the lightest hand units in its class, providing unrivaled comfort during a long working day.

ALEXA Remote Control
An optional software license will enable you to remote control all ALEXA Plus type cameras, except the ALEXA HD Plus. This includes setting frame rate, shutter angle, exposure index, false color on the monitor output, and more. Extended camera status information is also available, allowing you to quickly check your camera settings at any time.

Vibrating Markers
Tactile vibrating feedback lets you keep your eye on the action in the most challenging situations. Operators can concentrate on the scene, knowing that the hand unit will vibrate to prompt them when focus markers are reached.

Backlit Focus Knob
The super-smooth focus knob contains an integrated light source that shines through the wide, optionally pre-marked focus ring in low light conditions, thus providing clearly readable focus marks at all times. The friction of the focus knob can be easily adjusted to one’s personal preference without any tools.

Easy-to-Read Lens Data Display 
Clearly arranged, easy-to-read lens and camera information is available on the large 3” display, along with data from optional ultrasonic distance measurement devices. The transflective display technology ensures perfect readability in all ambient lighting conditions.

Pre-Marked Focus Rings 
Lens scales can be mapped to a set of high quality pre-marked focus rings in metric or imperial scale.

Focus Tracking 
The WCU-4 user button can be configured to activate focus tracking - setting the focus motor to continuously follow a subject by using an ultrasonic distance measurer. Focus tracking works with ARRI's Ultrasonic Distance Measure UDM-1 and the Universal Motor Controller UMC-4.

Personalized Settings
Various parameters of the WCU-4 can be set up to one’s personal preference. These include the display arrangement, vibration patterns and programmable user button, to name just a few. You can save your preferred settings on an SD card, enabling you to immediately personalize any WCU-4, anywhere in the world. 

Exceptional Quality and Service
The WCU-4 is completely splash-proof and embodies the reliability and durability for which ARRI is famous. Wear and tear parts are replaceable at rental level, and the worldwide ARRI Service network ensures rapid second level support if needed. New firmware versions can be installed to the unit via SD card within seconds.
