ARRI WCU-4 Wireless Follow Focus

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. With the ALEXA remote control software, you can set frame rate, shutter angle, exposure index, false colour on the monitor output, and more; all remotely. Extended camera status information is also available, allowing you to quickly check your camera settings at any time.

Noteworthy Attributes:

  • Tactile vibrating markers lets you keep your eye on the action in the most challenging situations.
  • The super-smooth focus knob contains an integrated light source that shines through the wide, optionally pre-marked focus ring in low light conditions, providing clearly readable focus marks at all times.
  • 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.
