K&F Concept Nano-C HMC UV-filter 77 mm

The K&F Concept Nano-C HMC UV Filter is a high-quality lens accessory designed for photographers who demand superior protection and image clarity. Crafted with Japanese AGC optical glass and advanced Nano-C Hard Multi-Coating (HMC) technology, this filter effectively reduces UV light and atmospheric haze while providing over 99.6% light transmittance. Its ultra-slim aviation aluminum alloy frame minimizes vignetting, and the double-threaded design allows for stacking additional filters or lens caps. Waterproof, oil-proof, and scratch-resistant, it ensures reliable performance in various conditions.

Advantages

This UV filter offers exceptional protection for your lens without compromising image quality. The 28-layer multi-coating (14 layers per side) reduces reflections and flare, while the ultra-slim 3.3 mm frame prevents vignetting on wide-angle lenses. The double-threaded ring allows easy attachment of other filters or lens hoods. With its durable construction and high light transmittance, it is an essential tool for preserving lens integrity and enhancing outdoor photography.
