K&F Concept Filtro ND variabile ibrido 2-in-1 CPL + ND2-ND32 49mm KF01.2595

The K&F Concept 2-in-1 Hybrid Filter combines a Circular Polarizer (CPL) and a Variable Neutral Density (ND) filter in a single ultra-slim frame. Designed for 49mm lens threads, this filter allows photographers to reduce glare, enhance color saturation, and control exposure from ND2 to ND32 (1 to 5 stops) with smooth 360° rotation. Crafted from Japanese AGC optical glass with 28 multi-layer coatings, it is waterproof, oil-proof, scratch-resistant, and anti-reflective. The aviation aluminum alloy frame prevents vignetting on wide-angle lenses.

Advantages

This hybrid filter eliminates the need to stack filters, saving time and reducing the risk of vignetting. The variable ND range provides flexibility in changing light conditions, while the CPL effect enriches colors and reduces reflections. The double-threaded design allows for additional filters or lens caps.
