The Polar Pro Cinema Series 6-Filter Pack for DJI Mavic Air is designed for enhancing motion rendering in your Mavic Air's recorded video footage. ND4, ND8, and ND16 filters, in both polarized and non-polarized versions, comprise this kit, providing 2, 3, or 4 stops of light reduction either with or without polarization. Use the polarized filters to reduce reflections and enhance the appearance of skies and water, and increase color saturation. These Cinema Series filters feature coated, production-grade glass and Polar Pro's signature lightweight AirFrame aluminum construction that doesn't affect the drone's gimbal operation. A protective hard carrying case is included to hold the six included filters.
