1. Using SCHOTT optical glass, precision grinding, high-definition imaging 2. Double-sided super waterproof coating, anti-fouling and scratch-resistant, effective protection 3. UV protection lens: used for shooting in the seaside, mountains, snowfields and open spaces, etc., it can reduce the blue tone caused by ultraviolet rays, and can also eliminate the interference of ultraviolet rays on the CCD 4. CPL: mainly used to eliminate harmful non-metallic reflected light, increase color density, improve the clarity and expressiveness of the picture 5. ND filter: prevent overexposure in strong light environment and resist scattered light 6. NDPL: Combines the advantages of ND light reduction and PL polarizer, eliminates reflections, enhances contrast, and makes the picture more three-dimensional 7. Anti-light pollution filter (Night): Effectively reduce light pollution and make the picture show true color 8. Star: There will be a starburst effect when shooting where the light is brighter 9. Material: frame lightweight aluminum + optical glass
