1. Using Schott optical glass, precision grinding, high-definition imaging
2. Double-sided super waterproof coating, anti-fouling and scratch-resistant, effective protection
3. Tooth-like touch, 360-degree adjustable, no vignetting and higher definition
4. Non-destructive quick disassembly and assembly; ultra-light and strong, stable flight
5. Night anti-light pollution: effectively reduce light pollution and make the picture show true colors
6. Star light mirror: there will be starburst effect in places with brighter lights
7. NDPL: combine ND and PL lenses to eliminate reflections, increase saturation, enhance contrast, and make the picture more three-dimensional and transparent; reduce the shutter speed, prolong the exposure time, and prevent overexposure
8. ND filter: prevent overexposure in strong light environment and resist scattered light
9. UV protection lens: used for shooting in environments such as seaside, mountains, snow fields and open areas, it can reduce the blue tone caused by ultraviolet rays, and can also eliminate the interference of ultraviolet rays on CCD
10. CPL: It is mainly used to eliminate harmful non-metallic reflection light, increase color density, and improve the clarity and expressiveness of the picture
11. Brushed filter: low-key to achieve a film-like brushed effect, producing retro horizontal glare flares
12. Mirror material: multi-layer coating process + optical glass
13. Frame material: lightweight aluminum
14. Size: 37x31.5x4mm
