KF 2-in-1 Filter Set Black Diffusion 1/4 and 1/8 K&F Concept 49mm

The KF 2-in-1 Filter Set combines a Black Diffusion 1/4 and a Black Diffusion 1/8 filter in a single kit, designed for lenses with a 49mm filter thread. Crafted with high-definition optical glass and aviation aluminum alloy, these filters soften highlights, reduce contrast, and diffuse light to create a cinematic look. Ideal for portrait and video work, they smooth skin tones and minimize blemishes while maintaining neutral color balance.

Advantages

This set offers two diffusion strengths in one package, allowing creative flexibility. The multi-layer nano-coating provides water-repellent, oil-repellent, and scratch-resistant properties, ensuring durability and easy cleaning. The ultra-slim frame prevents vignetting on wide-angle lenses.
