This Freewell filter uses optical glass with multi-layer coating, designed for outdoor drone shooting where dust, fingerprints, and moisture are common. The coating helps protect the glass surface and keeps the image more color neutral, so the filter effect comes from the mist diffusion rather than an unwanted color cast.
For clients, the important point is simple: the filter is made to create a softer highlight glow while still keeping the footage usable and controlled. It is not a cheap plastic cover or a heavy accessory. It is a camera filter built for the DJI Air 3S lens system, with a lightweight frame intended to keep normal gimbal movement stable.
