1. Ultra-thin and large-diameter: the bracket thickness is 12mm, and the 91mm ultra-large clear aperture effectively reduces the chance of vignetting when using an ultra-wide-angle lens.
2. Convenient to take, refuse light leakage, the rear CPL flexibly solves the pain points of filter stacking, and after removing the CPL, the cover can be closed to prevent light leakage.
3. ND8/ND64/ND1000 imported optical glass, 28-layer nano-coating technology.
4. Double-sided polishing process, showing high-definition picture quality.
5. ND8/ND64/ND1000, respectively dimming 3 gears/6 gears/10 gears dimming, multi-layer nano-coating, dustproof, waterproof, antifouling, anti-scratch, and protect the lens.
6. The square filter frame is helpful to protect the lens from accidental falling (the lens will not be broken when it is dropped to a flat ground from a height of 1.5 meters. Note: the frame cannot protect the lens from falling on a sharp convex surface)
