K&F 49MM, Nano-X, optical glass, soft gradient GND16, ultra-clear K&F Concept

Podrobný popis

The K&F Concept 49mm Nano-X Soft Gradient GND16 Filter is a high-quality circular neutral density gradient filter designed to balance high-contrast lighting between sky and ground. Made from Japanese optical glass with precision coatings and an ultra-thin aluminum frame, it delivers sharp, clear, and vignette-free landscape images.

The K&F Concept 49mm Nano-X Soft Gradient GND16 Filter is engineered for photographers who frequently shoot high-contrast outdoor scenes where the sky is much brighter than the ground. Soft gradient ND16 technology allows partial area dimming, balancing the exposure between bright skies and darker foregrounds, avoiding overexposure of highlights while preserving shadow details. Crafted from premium Japanese optical glass, the filter features precision grinding and double-sided polishing to maintain telephoto sharpness and high-definition imaging. Its thin, 5.3mm aviation-grade aluminum frame with CNC trapezoidal patterns ensures easy installation and rotation without vignetting on wide-angle lenses. The filter surface is enhanced with advanced Nano-X coatings, providing waterproof, anti-grease, anti-scratch, and moldproof properties, while maintaining optical clarity. With 4-level (1.2) dimming, 6.25% transmittance, and industry-leading low reflectivity (1.5%), this filter is ideal for landscape photography, delivering stable, accurate color and superior image quality under varied lighting conditions.
