K&F CONCEPT VARIABLE ND2-400 NANO-X 55MM FILTER NANO-X SERIES

The K&F CONCEPT Variable ND2–400 Nano-X 55mm Filter is a premium, professional-grade variable neutral density filter engineered for photographers and videographers who demand total exposure control without compromising image quality—even at 8K resolution. Offering smooth, stepless light reduction from 1 to 9 f-stops (ND2–ND400), this filter allows you to extend shutter speeds, shoot wide open apertures in harsh daylight, and achieve cinematic motion blur with absolute precision. Crafted from high-precision Japanese AGC optical glass with double-sided polishing and advanced 28-layer multi-coating, the Nano-X filter delivers exceptional clarity, high light transmission, reduced reflections, and minimal ghosting. Housed in an ultra-slim 7.4mm aircraft-grade aluminium frame with a smooth rotation mechanism and a high-visibility orange control tab, it ensures effortless adjustment, reliable performance, and reduced vignetting—even on wide-angle lenses. Durable, lightweight, waterproof, and scratch-resistant, this all-in-one Variable ND filter is the perfect creative tool for landscape, travel, portrait, and video shooters looking to master light in any condition.
