Filtro Híbrido 3-em-1 K&F Concept 37mm: ND Variável ND2-32 + CPL + Black Diffusion 1/4

The K&F Concept 37mm 3-in-1 Hybrid Filter combines a Variable Neutral Density (ND2-32) filter, a Circular Polarizer (CPL), and a Black Diffusion 1/4 filter into a single, ultra-slim frame. This innovative design allows photographers and videographers to control exposure, reduce glare, and add a cinematic softness to their images without swapping filters. Crafted with high-definition optical glass and multi-layer nano-coating, it offers water-repellent, oil-resistant, scratch-resistant, and anti-reflective properties. The aviation-grade aluminum alloy frame ensures durability while maintaining a lightweight profile. Ideal for lenses with a 37mm filter thread, this filter is perfect for achieving professional-quality results in various lighting conditions.

Advantages

This hybrid filter simplifies your gear by combining three essential filters into one. The variable ND function allows seamless adjustment from 1 to 5 stops of light reduction, enabling smooth exposure control even in bright environments. The CPL effectively reduces reflections and enhances color saturation, making skies bluer and foliage greener. The Black Diffusion 1/4 softens highlights and reduces contrast, adding a dreamy, cinematic look to your photos and videos. The multi-layer nano-coating protects the glass from dust, water, and scratches, ensuring long-lasting performance.
