Filter set. Specifically made for the Mavic 2 Zoom. This set includes ND4, ND8, ND16 and ND32 filters. ND filter reduces the amount of light coming into the sensor, giving you the freedom to create your own work by allowing more control of the camera's aperture, exposure time and sensor sensitivity settings. ND filter helps avoid overexposed photos. The ND4 filter allows 1/4 of incoming light through. The ND8 filter allows 1/8 of incoming light through. The ND16 filter allows 1/16 of incoming light through. The ND32 filter allows 1/32 of incoming light through.
