Specially made for the Mavic Air. This set includes ND4, ND8, and ND16 filters. ND filters reduce the amount of light coming into the sensor, giving you the freedom to create your work by allowing more control of the camera's aperture, exposure time, and sensor sensitivity settings. Put more simply; ND filters help avoid overexposure. 
The ND4 filter allows 1/4 of incoming light through, equal to a 2-stop filter.
The ND8 filter allows 1/8 of incoming light through, equal to a 3-stop filter.
The ND16 filter allows 1/16 of incoming light through, equal to a 4-stop filter.

Reduces light by 2/3/4 stops to effectively avoid over exposure, so that you can capture great photos in a wider range of environments.
