K&F Concept Nano-X MRC Hybrid Filter 3-in-1 77mm Fader ND2-32 + CPL + Black Diffusion 1/4

The K&F Concept Nano-X MRC Hybrid Filter 3-in-1 combines a variable neutral density filter (ND2-32), a circular polarizer (CPL), and a Black Diffusion 1/4 filter in a single 77mm frame. This innovative design allows photographers and videographers to control exposure, reduce reflections, and add a cinematic mist effect without swapping filters.

Advantages

Three essential filters in one: variable ND for exposure control, CPL for color saturation and glare reduction, and Black Diffusion 1/4 for softening highlights and creating a dreamy look. The 28-layer multi-nano coatings ensure waterproof, oil-proof, scratch-resistant, and anti-reflection performance. The ultra-slim aviation aluminum alloy frame minimizes vignetting even at wide angles.

Suitable for

• Landscape photography with long exposures
• Video recording requiring precise exposure control
• Portrait and creative photography with soft-focus effects
• Reducing reflections on water, glass, or foliage
