1. Non-destructive quick disassembly and assembly 2. Lightweight design, strong and durable 3. High definition light transmission, prevent overexposure 4. Using Schott optical glass, precision grinding processing, high-definition imaging 5. Double-sided super waterproof coating, anti-fouling and anti-scraping, effective protection 6. Starlight mirror: the effect of starlight will appear in the place with bright light 7. NDPL: the combination of ND and PL lenses can simultaneously meet the requirements of reducing the degree of exposure and eliminating non-metallic reflection; The higher the ND value, the higher the attenuation degree and the darker the picture 8. Light damage resistance: It is mainly shot at night scenes such as cities, which can effectively reduce light pollution and make the picture present real colors 9. CPL: mainly used to eliminate harmful non-metallic reflected light, increase color concentration, improve the clarity and performance of the picture 10. UV protective mirror: filter ultraviolet and stray light, show more real color; Prevent dust, oil, fingerprints and direct contact with the lens, effectively protect the lens 11. ND reducing lens: prevent overexposure in strong light environment, resist the scattered light, the greater the ND value, the higher the degree of reduction 12. Applicable models: for Mini 3 Pro 13. Material: aviation metal aluminum + optical glass 14. Weight: 1.4g/pc
