DJI CP.RN.00000185.01 LiDAR Range Finder for Ronin 4D

The DJI LiDAR Range Finder is a purpose-built focusing accessory for the Ronin 4D cinema camera system, designed to replace the uncertainty of manual focus with measurable, real-time precision. By emitting up to 43,200 ranging points across a 10-meter detection field, it maps the distance of everything in the scene and feeds that data directly to the Ronin 4D's autofocus system. The result is fast, confident focus acquisition that works even in challenging conditions — low light, low contrast, and scenes with minimal texture where conventional autofocus systems typically hunt or fail.

What sets this accessory apart is DJI's visualized LiDAR Waveform, which renders the ranging data as an intuitive top-down display on both the main and remote monitors. Operators can see exactly where focus is landing and make micro-adjustments with extreme precision, a capability that proves invaluable for solo shooters and small crews who may not have a dedicated focus puller. The unit connects to the Ronin 4D via the included focus motor cables and integrates seamlessly with the Zenmuse X9-6K and X9-8K cameras. For Ronin 4D owners looking to elevate their focusing accuracy and speed, the LiDAR Range Finder is a specialized tool that addresses one of cinema production's most persistent technical challenges.
