The ARRI WCU-4 (Wireless Compact Unit) is an industry-standard, 3-axis handheld wireless controller designed for precise, remote control of lens focus, iris, and zoom on professional motion picture sets. Though it has been officially designated as a legacy product by ARRI, it remains a highly sought-after and reliable workhorse among Focus Pullers and First Assistant Directors globally.

KEY HIGHLIGHTS:

• 3-Axis Control: Simultaneously controls focus, iris, and zoom motors.
• Lens Data Display: Features an integrated backlit display showing exact lens data, enabling easy tracking without direct sight of the physical lens markings.
• Camera Remote Settings: When paired with supported licenses and compatible camera bodies, it allows users to remotely adjust frame rates, shutter angles, exposure index, and white balance from afar.
