Key Features

1. 2-in-1 Multi-function Filter
   The K&F Concept ND8-128 & Black Mist 1/4 Filter combines two powerful functions in one filter. The ND8-128 feature allows you to reduce the amount of light entering your lens, which is perfect for long exposure shots, such as smooth water effects or capturing motion blur. The Black Mist 1/4 feature introduces a subtle soft glow to highlights and lowers contrast, giving your photos and videos a dreamy and cinematic look, ideal for portraits or video shoots.
2. Thin Frame & Large Friction Design
   This filter is designed with a CNC trapezoidal pattern on the frame to ensure a large area of friction, making it easy to install and remove the filter or any other accessories quickly and securely. The frame is constructed from aviation-grade aluminum, making it both lightweight and durable. The 7.4mm thin frame design ensures that you won’t experience vignetting, even when shooting at wide-angle or telephoto ranges.
3. 28-Layer Coating & 84% Transmittance
   The optical glass of this filter is equipped with a 28-layer anti-reflection coating on both sides, which minimizes reflection and ensures 84% light transmittance. The filter’s anti-reflection coating prevents glare and ghosting, resulting in sharp, clear images. The glass is finely ground and polished to maintain a stable molecular structure, preserving the sharpness of your lens and ensuring high-definition imaging for telephoto shots.
4. Adjustable Light Reduction (3-7 f-stop)
   The filter offers a 3-7 f-stop adjustable light reduction range, providing flexibility in controlling the exposure levels for various lighting conditions. This adjustable range allows you to fine-tune the filter for different shooting scenarios without worrying about the common issue of black cross effects that can appear in other variable ND filters.
5. Coating for Protection
   The double-sided coating provides excellent protection against external elements. It is waterproof, anti-scratch, and anti-oil, ensuring that your filter stays clean and functional even in challenging conditions. If the filter becomes contaminated with water droplets or oil, it can be easily cleaned, preserving its clarity and performance.
