K&F Concept Nano-X Series 77mm Variable ND2-ND32 + Black Diffusion 1/4 2-in-1 Filter — 28 Multi-Layer Coatings

Two filters in one: this K&F Concept Nano-X Series piece combines a Variable ND (ND2–ND32) with a Black Diffusion 1/4 effect, letting you control light (1–5 stops) while adding a cinematic soft glow to stills and video. Optical construction: made from Import Japanese AGC Glass and finished with double side polishing technology to preserve HD clarity and edge-to-edge sharpness, including when used on wide-angle lenses. Transmittance remains at the standard 84% with the diffusion element. Anti-artifact design: frame-self locked technology prevents the common "X" cross artifact found with some variable ND filters on wide-angle lenses. Handling and mount: the CNC non-slip frame provides secure grip for smooth installation and removal. Durability and cleaning: the filter features double-sided, 28 multi-layer coatings to cut internal reflections and offer waterproof, scratch-resistant, and oilproof protection for easy cleaning and long life. Compatibility and ordering note: fits all 77mm lenses — verify your lens thread size (usually stamped on the lens barrel or under the lens cap, indicated by the ø symbol) before purchasing. New and old packaging may be shipped at random.
