K&F Concept K&F 49MM XV40 Nano-X Variable ND Filter

The K&F 49mm XV40 Nano-X is a variable ND8 to ND128 filter designed to eliminate the common X cross issue. It is made with imported AGC glass and features 32-layer nanometer coatings for superior image quality, all within an ultra-slim frame to prevent vignetting.

This professional-grade tool allows precise control over light, adapting to different lighting conditions without changing filters. The filter is crafted from high-quality imported AGC glass for exceptional color fidelity and sharpness, ensuring no color cast affects your images. The glass is protected by NANOTEC multi-layer nanometer coatings (32 layers), making it waterproof, scratch-resistant, and anti-glaring. The 7.4mm ultra-slim frame prevents vignetting, even with wide-angle focal lengths as low as 32mm. The CNC non-slip design makes it easy to install and remove. Compatible with all 49mm lenses, a 52mm lens cap or hood is recommended.
