WCU-4 Wireless Follow Focus - 2 Channel

Camera Control License Installed

If you would like to use the WCU-4 with a non-Arri camera, please inquire about our AMC-1 Motor Driver.

Three Axes - All Inclusive
The Wireless Compact Unit WCU-4 combines three axes 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.

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.
