Cover various lighting conditions with just one filter, thanks to the PolarPro Cinema Series Variable ND Filter for Mavic Air 2 (ND4-ND32). ND filters are designed to minimize the amount of light entering the camera lens. This filter reduces light by 2 to 5 stops, ideal for various lighting conditions, from cloudy to extremely bright days. Adjust the filter with a simple rotation instead of wasting time changing different filters. It's practically like having the ND4, ND8, ND16, and ND32 filters in one. This lightweight filter is made of aerospace aluminum and Cinema Series optical glass to ensure durability against adverse weather conditions.
