K&F CONCEPT 46MM NANO C Series-3-in-1 Multi-Function Variable ND2-32&CPL& Black Mist 1/4, anti-refle

The K&F Concept 46mm Nano-C Series 3-in-1 Multi-Function Filter combines a Variable ND2-32, CPL, and Black Mist 1/4 diffusion in a single compact design—offering smooth exposure control, glare reduction, enhanced color, and cinematic soft-light effects without black “X” artifacts for professional photography and videography.

The K&F Concept 46mm Nano-C Series 3-in-1 Multi-Function Filter is an all-in-one hybrid solution for photographers and filmmakers who require precision, creativity, and convenience. This versatile filter combines three essential tools: a variable ND2–32 grey filter, a CPL circular polarizer, and a Black Mist 1/4 diffusion filter. The variable ND2–32 filter allows smooth adjustment of exposure up to 5 stops, enabling long-exposure effects and control of bright lighting conditions while avoiding the black “X” effect common in many variable NDs. The CPL element reduces reflections from water, glass, and other non-metallic surfaces while boosting color saturation and contrast, perfect for landscape photography. The Black Mist 1/4 diffusion softly lowers contrast, smooths skin imperfections, and adds a subtle cinematic glow, ideal for portraits and video work.

Constructed from high-quality Japanese AGC optical glass with 28-layer double-sided nano coatings, the filter provides water, dust, oil, and scratch resistance while ensuring maximum light transmission and minimal distortion. The lightweight CNC-machined anodized aluminum frame provides durability, precise fit, and anti-reflective performance. Compatible with 46mm lens threads, this professional-grade filter is a compact and reliable tool for enhancing creativity and image quality in a wide variety of shooting scenarios.
