Before buying, confirm that your drone is the DJI Air 3S. This filter is made for the Air 3S camera fit, so it should not be treated as a universal DJI filter for Mini, Mavic, Avata, Osmo, or older Air models.
Also check whether you want a creative effect filter or exposure control. The Black Glow Mist 1/4 is mainly for softening highlights and reducing harsh contrast. It is not the same as an ND filter for lowering shutter speed in bright sun, and it is not a polarizer for cutting reflections. If your goal is cinematic softness and highlight bloom, this is the right type to consider.
