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 ALEXA Plus or Studio cameras or the Universal Motor Controller UMC-4.

Multiple Mounting Options
The Wireless Compact Unit WCU-4 features M4 mounting points on its top and bottom, and the optional
WCU-4 Plate (K2.0006501) can attach to either, providing various 1/4-20 UNC and 3/8-16 UNC mounting
points itself. When mounted on the bottom, the WCU-4 Plate serves as a table stand or can be used to accept
a 3/8-16 UNC spigot for mounting on a C-stand. When mounted on top, it can be used to adapt the WCU-4
to an on-board monitoring system. Weighing only 67 g, the WCU-4 Plate is made of durable, aircraft-grade
aluminum.

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.
