The ARRI ZMU-4 Zoom Controller is a wired or wireless zoom control unit designed for modern ARRI ECS workflows. It features a force-sensitive joystick, a high-contrast lens-data and status display, a dedicated run/stop button, and built-in LBUS and CAM ports for lens and camera control. In its basic configuration, it can drive cforce motors directly over LBUS, and with a radio module installed it can transmit and receive signals across ARRI ECS systems for more flexible on- or off-camera operation.
