商品特点
- • 82mm ND1000滤光片采用优质日本光学玻璃制成，透光率高，无偏色; 航空铝合金框架，超薄轻巧，避免广角镜头渐晕。超坚固的框架确保耐用性和防止干扰。
- • 通过10个顶部，长时间曝光边缘工具减少光量;多层涂覆纳米滤光片，有效减少光线表面的反射，提高图像质量。
- • 18层多重涂层技术，显着减少镜头眩光和鬼影，同时使滤镜防划伤，防水，防油和防尘，适合冒险摄影的严苛考验
- • 硬涂层多层涂层工艺可抑制重影，闪光和反射，并增加透光率; 可用于在白天实现超慢速快门，使移动物体不可见
- • 可以使用慢速快门记录瀑布等物体的运动，为流动的水提供丝般顺滑的效果。
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.
