Achieve cinematic still photographs with this ND2000 Long Exposure Filter for DJI Mavic Air from Freewell. This ND2000 neutral density (ND) filter can reduce the amount of light from entering the lens by 11 stops, letting you capture long exposure images in extremely bright conditions. It's constructed from a durable aluminum alloy that's lightweight enough to not negatively affect the gimbal's performance, but strong enough to withstand outdoor conditions. To help achieve the best image results possible, Freewell utilized optical glass in the filter's construction and gave each side eight layers of optical coating.
