K&F CONCEPT VARIABLE ND2-400 NANO-X 49MM FILTER NANO-X SERIES

K&F CONCEPT VARIABLE ND2–400 NANO-X 49MM FILTER – PROFESSIONAL 1–9 STOP VARIABLE ND FOR 8K CAPTURE

The K&F Concept Variable ND2–400 Nano-X 49mm Filter is a premium, ultra-precise exposure-control tool engineered for photographers and filmmakers who demand maximum versatility and uncompromising optical quality. Delivering 1–9 stops of variable light reduction, this filter gives you the freedom to shoot wide open in harsh daylight, extend shutter speeds for silky motion blur, and fine-tune exposure for cinematic video—all through a smooth, intuitive rotation. Built from Japanese AGC high-precision optical glass, double-polished for 8K clarity, and enhanced with 28-layer Nano-X coatings, it ensures superior light transmission, minimized reflections, and edge-to-edge sharpness with zero color shift. Its slim 7.4mm aircraft-grade aluminium frame prevents vignetting on wide-angle lenses, while the integrated orange rotation tab provides precise control even in fast-paced shooting. Waterproof, scratch-resistant, and engineered for long-term durability, this variable ND is the ultimate all-in-one solution for creators—replacing multiple fixed NDs and unlocking creative flexibility whether shooting landscapes, portraits, travel, or cinematic video. Complete with a premium PU leatherette magnetic case, the Nano-X ND2–400 ensures your filter stays protected, accessible, and always ready for your next shot.

KEY FEATURES:
