Add to Gear List

The ARRI WCU-4 Wireless Compact Unit is a 3-axis handheld controller featuring an integrated lens display. The ARRI WCU-4 is one of the lightest hand units on the market, weighing just ~1.7 lb (including the battery). It provides durable, all-day comfort and reliable, 3-axis lens control (iris / zoom / focus) and remote start/stop recording, and other camera settings. The WCU-4 is compatible with the ARRI ALEXA Mini, ALEXA Plus, and Studio cameras, and with ARRI UMC-4, SMC-1, EMC-1, and AMC-1 motor controllers. Camera functions are controllable for ARRI ALEXA Mini, Plus and Studio, and ARRI AMIRA when used with the UMC-4 motor controller.

Vibrating markers and a backlit display make it easy to use the WCU-4 in low light levels. Multiple 3/8″-16, 1/4″-20, and M4 mounting points enable you to attach the controller to a rig when convenient.

The smooth focus knob contains an integrated light source which shines through the wide focus ring in low light conditions to provide clearly readable focus marks. You can adjust the knob friction to your preference without use of tools. You can dim or brighten the illumination of the focus knob (and the display), as needed.

Well-arranged yet still easy-to-read lens and camera information can be viewed on the large 3” LCD on the unit body.

Transflective display technology ensures perfect readability in all ambient lighting conditions. You can find data from optional ultrasonic distance measurement devices here, too. Six soft buttons below the LCD change their behavior depending on screen content. A convenient label will appear above the buttons at the bottom of the screen. If there is no label, that button has no function from that screen.

This controller includes the ability to adjust frame rate, shutter angle, exposure index, false color on monitor output, ND filter (on/off), and white balance.

Extended camera status information is also available for a quick confirmation of camera settings, such as battery levels (with intelligent batteries which feed data to the camera), which recording codec is in current use, plus the name of the lens attached.
