K&F Concept Black Diffusion 1/8 filter 67 mm

The K&F Concept Black Diffusion 1/8 Filter is a professional-grade lens filter designed to soften skin imperfections, reduce contrast, and create a cinematic soft glow. Crafted with Japanese AGC optical glass and a 28-layer Nano-X multi-coating, it delivers high light transmittance while being waterproof, scratch-resistant, and anti-oil/fingerprint. The ultra-slim 3.3mm aviation aluminum alloy frame prevents vignetting and is compatible with lenses featuring a 67mm filter thread.

Advantages

Enhance your portraits and videos with a natural, dreamy look. The 1/8 strength provides subtle diffusion without over-softening, maintaining image sharpness and color neutrality. The multi-coating reduces flare and ghosting, while the slim design allows use with wide-angle lenses.
