Arri WCU-4 Wireless Follow Focus


The Arri WCU-4 is a wireless, 3-channel “FIZ” unit that allows for control of a lens’ focus, iris, and zoom. It can connect correctly to the Alexa and Amira series of cameras, and when using a PL-mount lens, you can input lens information for more accurate control. The WCU-4 also has a backlit display and can be set to vibrate when hitting your focus marks.
