DJI Focus is a wireless follow focus system with a 100 m transmission range, composed of a remote controller hand unit, a single motor, connection cables, and fits inside an included hard case. Every slightest rotation of the control translates into immediate and precise rotation of the lens, thanks to the very high quality of construction. Wireless transmission is really fast: the DJI Focus wireless follow focus system allows operation up to 100 m with only 14 ms latency. While cinema lenses feature built-in hard stops, photography lenses do not. This follow focus allows you to set the focus points to your preference so that you can use any type of lens. Using the adjustment knob, you can customise the DJI Focus follow focus strength level to your needs.
