K&F Concept 77mm 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)

Features

• 【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 77mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. An 82mm lens cap is also required for this 77mm variable ND filter.
