K&F CONCEPT VARIABLE ND2-400 NANO-X 72MM FILTER NANO-X SERIES

The K&F CONCEPT Variable ND2–400 Nano-X 72mm Filter is a high-performance, professional-grade variable neutral density filter designed for photographers and videographers who demand precise exposure control and flawless image quality in bright shooting conditions. Fully optimised for UHD and 8K resolution capture, this premium filter offers smooth, stepless adjustment from 1 to 9 f-stops of light reduction, giving you the freedom to shoot wide apertures for creamy background blur or extend shutter speeds for cinematic motion effects—even in harsh daylight. Crafted from high-precision Japanese AGC optical glass and enhanced with 28 layers of Nano-X multi-coating, it delivers outstanding sharpness, accurate colour reproduction, minimal reflections, and high light transmission. The ultra-slim 7.4mm aircraft-grade aluminium frame ensures durability without added weight, reduces vignetting on wide-angle lenses, and features a smooth rotation mechanism with a high-visibility orange control tab for fast, intuitive adjustment. Rugged, waterproof, scratch-resistant, and beautifully engineered, the K&F Nano-X 72mm Variable ND filter is the ultimate all-in-one solution for mastering light and unlocking your creative potential in both photography and cinematic video production.
