The PD Movie Remote Air Pro 3 Dual-Channel Wireless Follow Focus System includes a single wireless receiving motor, a single slave motor for controlling a second lens function, and a handwheel that integrates focus, zoom, and iris control. The handwheel has a wireless range of 328' and supports 19 wireless channels, allowing you to find the cleanest signal path even when using multiple motors in a FIZ (focus, iris, zoom) setup. An available iOS app allows you to control the system with your iOS device from up to 33' away.
