Arri WCU-4 Wireless Follow Focus

The Arri WCU-4 is a lightweight ergonomic hand unit offering 3 axis control with full lens data display and lens mapping. With multiple mounting options this is a compact and versatile system.

The ARRI WCU-4 Wireless Compact Unit is a 3-axis handheld controller featuring an integrated lens display. Control camera functions, focus, iris, and/or zoom from a distance, such as when shooting handheld or using a stabilizer, gimbal or crane. 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. This WCU-4 set includes the control unit, a hand strap, lanyard, and one marking disk. Use a non-permanent marker to add focus marks to the disk.
