K F Concept 82mm Variable ND Lens Filter ND2-ND400 (1-9 Stops) 18 Multi-Layer Coatings Adjustable Neutral Density Ultra Slim Lens Filter for Camera Lens (K-Series) Import Optical Glass: Crafted from premium AGC optical glass with an astonishing 18 multi-layer coatings, this ND filter reduces reflections and glare, ensuring superior image quality. 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 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 certain 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. 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. Compatibility Note: This ND filter suits all 82mm lenses. Check your camera's lens thread size (usually beside a "o" diameter symbol) before ordering. An 86mm lens cap is also required for this 82mm variable ND filter. Buy with confidence. Check out our reviews.
