Podrobný popis

The K&F Concept 77mm Black Mist 1/8 Filter (Nano-X Pro Series) features a brass CNC frame, ultra-low 0.15% reflectance coating and 36-layer nano protection on AGC optical glass for soft cinematic diffusion. It minimizes ghosting, smooths skin textures, and adds a dreamy glow to portraits and night shots while preserving detail, with water/oil/scratch resistance for durable, easy-clean performance.

The K&F Concept Nano-X Pro Series 77mm Black Mist 1/8 Filter is a professional-grade diffusion accessory engineered for cinematic photographers and videographers, blending subtle atmospheric haze with high-fidelity optics to elevate portraits, street scenes, and low-light footage. Its ultra-low reflectance coating (0.15% minimum, spectral range 400–700 nm) effectively suppresses flare and ghosting from intense light sources, ensuring natural mist diffusion without color casts or veiling glare, ideal for dynamic day/night transitions. The 1/8 density delivers a gentle soft-focus effect that delicately reduces skin imperfections—wrinkles, pores, and spots—while maintaining sharp subject details and overall contrast, creating a flattering. The precision CNC-machined brass frame (trapezoidal profile, 3.5 mm thickness) provides superior thread engagement (M77 x 0.75 pitch, <0.05 mm tolerance) and impact resistance (up to 1 m drop), with a matte black finish to minimize reflections. Protected by 36-layer nano coatings (hydrophobic >110°, oleophobic >95°, hardness 8H), it repels water, oil, scratches, and mildew for effortless maintenance—simply wipe with a microfiber cloth. Included suede pouch ensures elegant, scratch-free storage, making this filter a reliable companion for on-location shoots.
