【Putter Design for Precision】The frame is ingeniously designed as a putter, allowing you to accurately adjust the stop. Video shooting users can effortlessly adjust the stop with auxiliary tools. Every stop from ND2 to ND400 is conveniently marked on the frame, providing smooth 360-degree rotation for multi-scene applications.
【No Vignetting】Designed for ultra-wide-angle applications, the ultra-slim frame measures only 7.4mm, ensuring no vignettes even at a 16mm focal length.
【Import Optical Glass】Crafted from premium Japanese AGC optical glass with an astonishing 28 multi-layer coatings, this ND filter reduces reflections and glare, ensuring superior image quality.
The K&F Concept ND filter is fully protected with multi-layer coatings on both sides, making it waterproof and scratch resistant for adventurous use.
【Compatibility Note】This ND filter suits all 77mm lenses. Be sure to check your camera's lens thread size (usually beside a "ø" diameter symbol) before ordering. Additionally, an 82mm lens cap is required for this 77mm variable ND filter.
