Arri WCU-4 Wireless Lens Control – Video Tutorial

57 shows you how to set up and operate the new Wireless Control Unit (WCU-4) for giving you complete control over focus, iris, and zoom, on cinema lenses.



  1. Silly question, how does the unit know the lens info? I have Sigma CINE PL mount glass with no digital connector for lens info.

  2. Being forced to learn this thing for our crane camera. I can’t stand this thing. Not user friendly, stiff menus, worthless.

  3. what cameras did you use to shoot this video?
    colors and skin tone are excellent!

  6. i want to buy one cam for short film ……. if you have emi suitation plz contact me on . AKKI LINK on face book page . plz

    if you can't reply there ..i will block you ..bqz this is the last condition

  7. this is a great tool. but does anyone think eventually autofocus in cinema cameras is the future? already in some canon and sonys we can tap a face or object and get very accurate autofocus and tracking focus. seems like this will make life a lot easier for dps and camera ops.

  8. hello friends I am Cinematographer Pintu Verma from India really thanks for you all team you are good information

  9. Awesome Video really love the website too, Do you guys think you can do a video on the Arri Alexa XT Plus? I know its not exactly a new camera but there are zero overview videos like you guys do them.
