Optically manage the quality of your aerial footage by keeping a DJI 3-Piece ND Filter Set for Air 3S tucked away in your drone gear bag. These ND filters are designed to reduce the amount of light that enters the Air 3S’ dual-camera gimbal and reduce shutter speeds accordingly. The ND8, ND32, and ND128 filters reduce light by 3, 5, and 7 stops, respectively.
