K&F Concept 40.5mm Neutral Density Filter, 40.5mm Slim Variable Fader ND Filter Adjustable ND2 to ND400 Filter + Cleaning Cloth

Features

• 【Import Optical Glass】Crafted from premium AGC optical glass with 8 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: Max 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.
• 【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 40.5mm lenses. Check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. Additionally, a 43mm lens cap is required for this 40.5mm variable ND filter.
