Achieve superior light control and stunning image quality with our advanced ND filter! Imported Optical Glass: This ND filter is crafted from premium AGC optical glass, featuring 8 multi-layer coatings that reduce reflections and glare, ensuring exceptional image clarity. Versatile Light Control: Enjoy 1 to 9 stops of adjustable light reduction and 360-degree rotation for precise dimming settings, making this filter perfect for various scenarios. (Note: Maximum stops may cause a cross-pattern effect, commonly known as an 'X black cross.' This phenomenon is natural and temporary, occurring due to the adjustable ND filter's interaction with specific lenses and focal lengths.) Glare-Free Surface: Treated with an oxidized sandblasting process, this filter prevents unwanted stray light and minimizes unnecessary reflections on the metal surface, ensuring clean, crisp images. Slim and Secure: With a thickness of only 7.4mm, the CNC-patterned design enhances friction during rotation, making it easy to attach and detach lenses and accessories anytime, anywhere. Compatibility Note: This ND filter fits all 43mm lenses. Please check your camera's lens thread size (usually next to a 'ø' diameter symbol) before ordering. Additionally, a 46mm lens cap is required for this 43mm variable ND filter.
