K&F Concept Nano-X MRC CPL & Fader ND2-32 & Black Mist 1/4 - 40.5 mm

The K&F Concept Nano-X MRC 3-in-1 Combination Filter combines a Circular Polarizer (CPL), Variable Neutral Density (ND2-32), and Black Mist 1/4 diffusion into a single ultra-slim frame. Designed for photographers and videographers seeking creative control, this filter reduces glare, controls exposure, and softens highlights for a cinematic look. Crafted from Japanese AGC optical glass with 28-layer Nano-X multi-resistant coating, it offers hydrophobic, oleophobic, scratch-resistant, and anti-reflection properties. The 40.5 mm diameter fits compact cameras and lenses, with smooth 360° rotation and no vignetting even at wide angles.

Advantages

Three essential filters in one: CPL eliminates reflections, variable ND adjusts exposure from 1 to 5 stops, and Black Mist 1/4 adds a dreamy diffusion effect. The ultra-slim aviation-grade aluminum frame ensures no vignetting, while the Nano-X coating protects against water, oil, and scratches. Ideal for landscape, portrait, and video work.
