【Precision Optics】Crafted from top-tier Japanese optical glass with double-sided 24-layer enhanced coating, this filter reduces surface reflections effectively. This prevents glare caused by external reflections during prolonged exposures, ensuring impeccable image quality. | 【Enhanced Water Resistance】Featuring a multi-layer waterproof coating, even if water splashes onto the filter, it remains in droplet form, allowing for easy carrying and cleaning. | 【Versatile Light Control】With 1 to 9 stops of adjustable light reduction and 360-degree rotation for precise dimming settings, this filter is perfect for diverse scenarios. (Note: High settings may cause a cross-pattern effect, commonly known as a "black cross." This phenomenon is natural and temporary, occurring due to the adjustable ND filter's interaction with certain lenses and focal lengths.) | 【Slim and Secure】At a mere 7.4mm thickness, the CNC-patterned design ensures enhanced friction while rotating, making it easy to attach/detach lenses and accessories anytime, anywhere. | 【Glare-Free Surface】Treated with an oxidized sandblasting process, this filter prevents unwanted stray light and minimizes unnecessary reflections on the metal surface. NOTE: This ND filter suits all 77mm lenses. An 82mm lens cap is required for this 77mm variable ND filter.
