52mm,Nano-X,ND1000玻璃,超清,镀防水防刮增透绿膜
商品特点
- • 52mm ND1000 Filter made with premium Japan Optics glass, top level of transmittance, no color cast; Aviation aluminum alloy frame,super slim and lightweight, avoiding vignetting on wide angle lenses. Extra tough frame ensuring durability and jamming prevention.
- • Neutral Density Filter reduce the amount of light by 10 stops, long-time exposure edge tool;Multi-coated nano filter, effectively reduce the light refection of the surface, improve image quality.
- • 18-layer multi-resistant coating technology significantly reducing lens flare and ghosting while making the filter anti-scratch, water repellent, oil & dust resistant fit for the rigors of adventure photography.
- • Hard coated multicoating process suppresses ghosting, flare and reflections, and increase light transmission; Can be used to achieve super slow shutter speeds in daylight to render moving subjects invisible.
- • Enables slow shutter speeds to be used to record movement in subjects such as waterfalls, providing a silky smooth affect to flowing water.
ND FILTER
Reduces the amount of light entering the lens, thus decreasing camera shutter speed. Useful for situations where motion blur needs to be created (rivers, waterfalls, moving people) or large apertures must be used with flash to avoid overexposure.
