The 6-filter neutral density and ND/polarizer kit was put together by Tiffen for the DJI Mavic Air to offer multiple aperture and shutter speed options for Mavic Air operators. The kit comes with 0.6, 0.9, and 1.2 neutral density filters, which reduce light from passing through by 2, 3, and 4 stops, respectively, and 0.6, 0.9, and 1.2 ND/circular polarizer filters. The three neutral density filters create a darkening of the entire image, allowing you to photograph with a wider aperture to control depth of field or a slower shutter speed to convey movement more easily. In addition to providing neutral density effect, the three ND/polarizer filters allow an increase in contrast, and  they help control reflection and reduce glare. The ND/polarizer filters rotate to adjust the intensity of the effect. All six filters are made from optical glass with waterproof and scratch-proof multi-coating, which reduces reflection and maintains clarity and color fidelity. The filter mounts are made of aluminum and have a circular shape. The kit includes a cleaning cloth and a metal case to protect and carry the filters.
