The PGYTECH Circular Polarizer MRC Pro Filter for DJI Mavic 2 Pro Drones is made from SCHOTT optical glass, a lightweight aluminum frame, and has the added benefit of a multi-resistant five-layer coating. The MRC is designed to add much needed protection for your lens when shooting in inclement weather. Being a circular polarizer, this filter is mainly designed to reduce scattered light and the appearance of reflections in your images. It also can enhance color and increase the contrast of your footage.
