K&F Concept Nano-X Series 77mm Soft GND8 (3 Stop) Graduated Neutral Density Filter — 28 Multi-Layer Coatings

Purpose-built to balance bright skies with darker foregrounds, this 77mm Soft GND8 (3 Stop) filter prevents sky overexposure while preserving natural tones. Constructed from imported AGC optical glass to reproduce accurate colors, it provides 3 stops of light reduction and lowers surface reflectivity to 1.25% (other brands same filter is 2%). Both faces of the glass carry 28 multi-layer nanometer coatings that are waterproof, scratch-resistant and simple to clean. The advanced graduated coating maintains stable color and ensures precise, consistent light attenuation across the transition for clean, professional results. The filter is housed in a CNC-machined, non-slip aviation aluminum frame that makes installation and removal easier. Its 3.3mm ultra-slim profile is designed to minimize the risk of vignetting on wide-angle setups. New and old packages are sent randomly.
