ARRI’s Wireless System is a sophisticated toolset for wirelessly controlling lens and camera functions on set. The Wireless Compact Unit WCU-4 is the most sophisticated, feature-rich and user-friendly remote control on the market.
The compact and ergonomic hand unit controls up to three lens axes for focus, iris and zoom. It includes a super-smooth focus knob with adjustable friction and backlit focus rings that are easily readable in the dark. The large transflective display includes a lens data display, providing graphical focus, iris and zoom scales; camera status information; and readouts from ultrasonic measurement devices. A user programmable button underneath the handle allows rapid access to functions like quick zoom (zap) or the setting of digital focus marks. The optional hand strap provides extra stability and leaves the holding hand’s thumb free, allowing even the most challenging simultaneous shifts of iris and focus to be carried out with ease.
One of the coolest new features of the WCU-4 is the option to use vibration markers, which provide haptic feedback for focus marks. The unit will vibrate when a focus mark is reached, allowing ACs to keep their eyes on the performers at all times and leading to greater accuracy of focus.
