K&F Concept Nano-X Series Variable ND8-ND128 Filter 77mm

The K&F Concept Nano-X Series Variable Neutral Density Filter offers photographers precise exposure control with a density range of ND8 to ND128 (3 to 7 stops). Crafted with Japanese AGC optical glass and 28 multi-layer nano coatings, this filter is waterproof, oil-proof, scratch-resistant, and anti-reflective. The ultra-slim aviation aluminum alloy frame is CNC-machined for durability and eliminates vignetting. A unique design prevents the 'X' cross pattern at maximum density, ensuring clear images. The 360° rotation with hard stops allows easy adjustment, and the front 77mm thread enables stacking or lens cap use. Ideal for landscape, portrait, and video work, this filter maintains high-definition sharpness with minimal color shift.
