Account for nearly all lighting conditions, including extremely bright lighting, with this 2-pack of Variable ND Filters for DJI Air 2S from PolarPro. Each filter is a VND filter, which stands for variable neutral density. This means that each filter can be dialed in to a specific amount of light reduction. One filter can reduce light from two to five stops, while the other reduces light from six to nine stops. Laser-etched indicators help make the adjustment easy. As with most filming, including via drone, time is of the essence, so having quick adjustment abilities via two filters versus a larger set of single-value filters can help you save precious time and drone battery life.
