DJI Ronin 3D Focus System

The DJI Ronin 3D Focus System is an advanced autofocus accessory designed for DJI RS 2, RS 3, and RS 3 Pro gimbals, enabling continuous and precise focus when using manual lenses. By detecting the distance between the lens and subject, it delivers reliable center-point autofocus for professional filming workflows.

The Ronin 3D Focus System brings intelligent autofocus capabilities to manual lenses when paired with DJI RS-series gimbals. Mounted on top of the camera and used in combination with a compatible focus motor (sold separately), the system measures the distance between the lens and the subject in real time to enable accurate, continuous center-point autofocus. It can detect people at distances up to 19.7 feet (6 m) and objects up to 32.8 feet (10 m), ensuring reliable performance across a wide range of shooting scenarios. Designed for professional production environments, the system features a wide detection range, precise field of view, and USB-C connectivity for power and data. Compact, lightweight, and easy to mount, the Ronin 3D Focus System is ideal for filmmakers who want smooth, automated focusing with manual lenses on DJI gimbals.
