K&F 82MM,Nano-X, optical glass, soft gradient GND16 K&F Concept

Podrobný popis

The K&F Concept 82mm Nano-X Soft Gradient GND16 Filter helps balance extreme brightness differences between the sky and the foreground, ensuring well-exposed landscape images. Built with premium Japanese optical glass and advanced Nano-X coatings, it delivers ultra-clear, vignette-free performance for both wide-angle and telephoto lenses.

The K&F Concept 82mm Nano-X Soft Gradient GND16 Filter is designed for photographers who frequently capture outdoor scenes with significant brightness contrast—such as landscapes during sunrise, sunset, or bright midday skies. Due to the limited dynamic range of camera sensors, exposing for the sky often darkens the foreground, while exposing for the ground overexposes the sky.

This soft graduated filter solves this challenge by incorporating a smooth transition from clear to neutral gray, allowing you to selectively darken the brighter portion of the frame, typically the upper sky area. This helps balance overall exposure, reduce blown-out highlights, and preserve detail across the entire image.

Constructed from top-quality Japanese optical glass, the GND16 filter provides 4 stops (1.2) of light reduction with excellent optical performance. Precision grinding and double-sided polishing ensure molecular stability, maintaining sharpness and clarity—even with high-resolution cameras and telephoto lenses.

The advanced Nano-X multi-layer coating protects against mold, scratches, water, and oil. These coatings maintain image clarity while making the filter easy to clean, even when exposed to moisture or fingerprints during outdoor shooting.

The frame is engineered from durable aviation-grade aluminum with a slim 5.3mm profile to avoid vignetting on wide-angle lenses. Its CNC-machined trapezoidal grip pattern increases friction for easier rotation, installation, and removal in any shooting environment.

Using high-tech gradient coating technology, the filter provides accurate and uniform color, precise optical density, and stable tonal results for professional-quality landscape photography.
