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 glasses: used for shooting in the seaside, mountains, snowfields and open spaces, etc., 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. Starlight : There will be a starburst effect when shooting brightly lit places
7. NDPL: Integrate ND and PL lenses to meet the two needs of reducing exposure and eliminating non-metallic reflections at the same time
8. Material: aviation metal aluminum + optical glass
