KF filter K&F Concept Nano-X MRC CPL & Fader ND2-32 & Black Mist 1/4 – 52 mm

The K&F Concept Nano-X MRC CPL & Fader ND2-32 & Black Mist 1/4 is a versatile 3-in-1 filter designed for photographers and videographers who demand creative control. Combining a Circular Polarizer (CPL), a Variable Neutral Density (ND) filter with a range of ND2 to ND32 (1-5 f-stops), and a Black Mist 1/4 diffusion effect, this filter allows you to manage reflections, exposure, and cinematic softness in a single, high-quality optic. The 52mm thread size fits a wide range of lenses.

Advantages

This 3-in-1 filter eliminates the need to carry multiple filters, saving space and time. The CPL reduces glare and enhances color saturation, while the variable ND enables smooth exposure control in bright conditions. The Black Mist 1/4 diffusion softens highlights and reduces contrast for a cinematic glow, perfect for portraits and video. The Nano-X Multi-Resistant Coating (MRC) ensures water, oil, and scratch resistance, maintaining image clarity.
