K&F Concept 62MM Adjustable Black Mist 1/4 & ND8 128 Filter

The K&F Concept 62mm Adjustable Black Mist 1/4 & ND8128 Filter combines diffusion and variable ND functions in one compact design. Offering 37 stops of light reduction and cinematic soft-glow diffusion, it enhances both photos and videos with professional-grade clarity, smooth highlights, and controlled exposure.

This filter is designed for creators who want both diffusion effects and adjustable light control in a single filter. This 2-in-1 hybrid design works as a cinematic Black Mist 1/4 diffusion filter and a variable ND8128 filter, making it perfect for videographers, filmmakers, and photographers seeking versatility without carrying multiple filters.

The Black Mist 1/4 diffusion effect softens contrast, reduces digital sharpness, and gently blooms highlights to create a dreamy, film-like atmosphere. This helps achieve smoother skin tones, a softer overall mood, and enhanced flare aesthetics ideal for portraits, night scenes, and cinematic video production.

As a variable ND filter, it offers 37 stops of adjustable light reduction, giving you precise exposure control in bright environments. The built-in limit structure prevents over-rotation, eliminating the common X cross issue typical of variable ND filters.

Crafted from premium optical glass with 28 layers of anti-reflection coating on both sides, the filter achieves the industry-standard 84 transmittance of a Black Mist 1/4 filter while maintaining excellent color accuracy and sharpness. Fine grinding and double-sided polishing ensure molecular stability and high-definition imaging, even when used with telephoto lenses.

The frame is built from durable aviation-grade aluminum, featuring a slim 7.4mm design to prevent vignetting on both wide-angle and telephoto lenses. Its CNC-machined trapezoidal texture provides extra grip for smooth adjustments and easy installation or removal in any shooting scenario.

For added reliability, the Nano-coated glass is mold-resistant, waterproof, anti-scratch, and anti-oil, making it easy to clean even when exposed to fingerprints, rain, or dust.
