K&F Concept 67mm ND8-ND128 Variable Neutral Density Filter (3-7 Stop) Slim Multi-Coat NANO-X

Overview: K&F Concept 67mm variable neutral density filter ND8–ND128 (3–7 Stop) from the NANO-X series, designed to give precise exposure control without compromising image quality. Optical construction: Built with imported AGC glass — a premium filter material that preserves sharpness and avoids color cast for natural-looking results. Optical surfaces receive NANOTEC multi-layer treatment (28 layers in total) that is waterproof, scratch-resistant and anti-glare to protect your lens and improve image quality. Mechanical design: The filter uses a Self-Lock frame engineered to eliminate the common “X” cross artifact found on many variable NDs when used on wide-angle or telephoto lenses. The ultra-slim 7.4mm frame minimizes vignetting and supports shooting at 28mm focal length with no vignetting. A CNC non-slip finish makes mounting and removal quick and secure. Important: Confirm your lens thread size before ordering. The thread diameter is usually stamped on the lens barrel or printed under the lens cap and is preceded by the Ø symbol (for example Ø82 = 82mm, Ø72 = 72mm).
