K&F 49MM, multi -function can be adjusted black mist 1/4 & ND8 ~ 128

The K&F Concept 49mm Multi-Function Adjustable Filter combines a Black Mist 1/4 diffusion effect with a variable ND8–128 light-reduction range, offering photographers and videographers a versatile 2-in-1 solution in a single slim, high-quality unit. Designed with premium optical glass, 28-layer coatings, and an ultra-thin aviation-aluminum frame, it delivers smooth rotation, minimized reflections, and clean, high-definition imaging for both wide-angle and telephoto shooting.

The K&F Concept 49mm Multi-Function Black Mist 1/4 & ND8–128 Filter is engineered for creators who need flexibility without swapping gear. This innovative 2-in-1 filter functions both as a cinematic Black Mist 1/4 diffusion filter—softening highlights and adding natural glow—and as an adjustable ND filter offering 3 to 7 stops of light reduction (ND8–128). Precision-crafted from top-grade optical glass, it features a double-sided 28-layer anti-reflection coating that reduces flare, maintains 84% transmittance, and ensures razor-sharp clarity even at telephoto focal lengths. The 7.4mm ultra-thin frame, made from durable aviation aluminum, prevents vignetting across the zoom range, while the CNC-machined trapezoidal texture provides superior grip for smooth and controlled adjustments. With its anti-scratch, anti-oil, waterproof, and mildew-resistant coatings, this filter withstands demanding shooting conditions and stays easy to clean, making it an essential all-in-one tool for photography and cinematography.
