The Polar Pro Mavic Air Gradient Three Pack for the DJI Mavic Air drone creates the right exposure balance between the air and the ground. This kit contains the ND8-GR, ND16-4 and ND32-8 filters that reduce 2 to 3 stops slightly. This will correct your images during the golden hour, sunny days and cloudy days. The low shutter speed creates a cinematic effect without darkening the ground. Thanks to the Airframe construction, the filters remain in place, also high in the air. The filters are made of glass elements and coatings to prevent ghosting and reflections. You take the filters with you in the included case.
