Our Take

Best for: Solo filmmakers using manual lenses on DJI RS series gimbals.

The DJI RS 3D Focus System is a clever accessory for a specific type of filmmaker. If you use a DJI RS 3, RS 3 Pro, or RS 2 gimbal with manual-focus cinema lenses, this device can track a subject's distance and send that data to a separate focus motor. This creates an autofocus-like experience, allowing for smooth rack focuses that would be very difficult to pull manually while operating a gimbal. What stands out is its ability to new functionality from existing gear. Instead of investing in expensive autofocus lenses, you can add this capability to your favorite manual primes or zooms. The main limitation is its dependency on the full DJI ecosystem. It does nothing on its own; you must have both a compatible gimbal and the Ronin Focus Motor attached to your lens. Also, the effective tracking range is modest, maxing out at about six meters on a person. At this sale price, it's a worthwhile upgrade for the right user. It solves a real problem for solo shooters who need reliable focus while moving. If your kit is already based around a DJI gimbal and manual lenses, this system makes a lot of sense.

Price Analysis

At $40.70, this is a 32% discount off the recent 30-day average of $60.26. The 90-day and 180-day averages were over $73, making this the lowest price seen in at least six months. This is a very good time to buy if you need this accessory.
