The DJI LiDAR Range Finder for RS lets you add extra-precise autofocus when your camera is mounted on a DJI RS 3 Pro gimbal, even when you're tracking a fast-moving subject.

Enables auto focus on manual focus cameras and lenses, ideal for Black Magic etc.

I put this on a camera and never used it in action as I didn’t realise the range is limited to 14 metres. Works well but I changed to an autofocus ecosystem so this is not needed. Cost $850 and apart from a small screwdriver mark on the Mount bolt is absolutely as new in the box.
