K&F Concept 40.5MM Nano-X CPL+Variable ND 232 filter

The K&F 40.5mm Nano-X Multifunctional CPL + Variable ND 232 Filter combines a circular polarizer and variable neutral density filter in one lens accessory. It reduces light intake, controls reflections, and darkens skies, while eliminating the X cross issue often seen in wide-angle shots. Made from professional optical glass with multi-layer coatings, this filter ensures clear, high-quality images and durable lens protection.

This filter offers photographers and videographers a versatile 2-in-1 solution. Functioning as both a CPL polarizer, which reduces glare and enhances color saturation, and a variable ND filter with 2 to 32 stops of light reduction, it allows precise exposure control and creative flexibility.

Constructed from premium professional optical glass with multi-layer coatings, this filter delivers sharp images with minimal reflection, while being waterproof and scratch-resistant. The aluminum alloy frame features a serrated edge for secure grip and easy installation, and the ND adjustment is clearly marked from Min to ND32 for accurate light control. Advanced design prevents the X cross artifact, commonly seen in wide-angle variable ND filters, ensuring uniform image quality across the frame.

Ideal for landscape photography, long-exposure shots, and video production, this compact filter offers both lens protection and creative control in one convenient accessory.
