Constructed from double-sided, multi-coated optical glass, this lightweight ND64/PL Hybrid Filter for DJI Phantom 4 Pro/Pro+ from Freewell is designed to have the properties of both a neutral density filter and a polarizing filter. Ideal for bright and sunny conditions, this filter is made to reduce the amount of light that hits the sensor by 6 stops, and also has the effect of reducing glare from metallic surfaces.
