The WCU-4 is an advanced, three axis (focus/iris/zoom) hand controller with the ability to display detailed lens and camera information when used with Alexa Mini/Plus/Studio cameras and lenses that support metadata.
Set marks and configure the hand unit to vibrate when they are hit - a great way to concentrate on a scene while ensuring the shot is in focus. Vibrating alerts can also be set to tell the operator when the camera storage media is almost full or battery voltage is getting low (for Alexa Mini/Plus/Studio cameras).
The WCU-4 works as part of a wireless follow focus system built around either a standalone Arri UMC-4 / UMC-3A radio unit (or an Arri white radio compatible equivalent) or an Alexa Mini / Plus / XT Plus / Studio / XT Studio camera.
Use of a WCU-4 in a UMC-4 / UMC-3A configuration is ideal for a wide variety of camera systems - not just Alexa. When used this way, camera or lens metadata may not be displayed on the WCU-4, depending on the configuration used. Camera run control and status is available with use of the appropriate control cable for the UMC-4 / UMC-3A controller.
Full functionality is available when used with Alexa cameras with internal wireless receivers, such as Alexa Mini and Alexa XT Plus.
Our WCU-4 units include the optional license to control Alexa camera settings such as frame rate, shutter speed, exposure index, etc. Additional Alexa camera status information is also displayed on the WCU-4 with this option installed. Works with Alexa Mini / Plus / XT Plus / Studio / XT Studio.
