K&F 40.5MM Nano-X Multifunctional CPL+Variable/Fader ND 2~32 filter

The K&F 40.5mm Nano-X Multifunctional CPL + Variable ND 2~32 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.

The K&F 40.5mm Nano-X Multifunctional CPL + Variable/Fader ND 2~32 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.
