K&F 55MM,Nano-X, optical glass, soft gradient GND16, ultra-clear

The K&F Concept 55mm Nano-X Soft Gradient GND16 Filter is a high-performance circular ND filter that balances high-contrast outdoor scenes. Made with Japanese optical glass and a thin aviation-grade aluminum frame, it delivers ultra-clear, vignette-free images for professional landscape photography.

The K&F Concept 55mm Nano-X Soft Gradient GND16 Filter is designed for photographers tackling outdoor scenes with significant contrast between bright skies and darker foregrounds. Its soft gradient design—half-transparent, half-gradient gray—provides partial area dimming, balancing exposure and preventing overexposed highlights or underexposed shadows. Crafted from top-quality Japanese optical glass with precision grinding and double-sided polishing, this filter maintains sharpness even on telephoto lenses while delivering high-definition imaging. The CNC trapezoidal patterned frame ensures secure grip for easy rotation and convenient installation or removal. Advanced Nano-X coatings make the filter waterproof, moldproof, scratch-resistant, and anti-grease, without affecting image quality. The ultra-thin 5.3mm aviation-grade aluminum frame prevents vignetting on wide-angle and telephoto lenses, and high-tech gradual coating guarantees uniform color and precise dimming. Ideal for landscape photography, this filter enables professional results in high-contrast lighting conditions.
