Pull focus from up to 300' away with the DJI Focus wireless lens control system. This system is composed of a remote controller hand unit, a single motor, connection cables, as well as other extras, and fits inside an included hard case. While the Focus can function as a standard remote follow focus, it has a few tricks up its sleeve; using a separate cable, you can control the focus or iris of the lens mounted to your Inspire drone's Zenmuse X5 or X5R gimbal.
