Cover a wide range of lighting conditions with this Cinema Series Variable ND Filter Combo for Mavic Air 2 from PolarPro. Neutral density filters are designed to minimize the amount of light that enters a camera's lens. This set of two filters is crafted to reduce light by 2 to 5 stops and 6 to 9 stops respectively. This is ideal for cloudy to extremely bright days and for different visual effects, such as motion blur or long exposure shots. These filters can accomplish this thanks to their variable design. Rather than waste time swapping out filters as the light changes, you can leave each one on and adjust it with a twist. The 2 to 5-stop filter is equivalent to a set of ND4, ND8, ND16, and ND32 filters. The 6 to 9-stop filter is equivalent to a set of ND64, ND128, ND256, and ND512 filters.
