This CPL, ND Filter Kit from Neewer is designed for the DJI Mini 3/Mini 3 Pro drones. It includes CPL, ND8, ND16, ND32, ND64, and ND128 filters for use in varying outdoor conditions from slightly cloudy to extremely bright sunlit days. The CPL filter avoids glare and reflections from reflective surfaces. Additionally, five ND filters reduce the amount of light that enters the lens by 3 to 7 stops to let you capture more accurate images with dynamic motion blur. Neewer has given these filters 30 layers of coating, making them waterproof, dustproof, oilproof, and scratchproof. They feature an optical glass construction\r\nwith a durable yet lightweight aluminum frame.
