KF Nano-X MRC UV Filter 77mm – Advanced Ultraviolet Protection, Ultra-Slim Aviation Aluminum Frame, Japanese AGC Glass, 28-Layer Multi-Resistant Coating

With a light transmittance exceeding 99.6% and 28 layers of Nano-X Multi-Resistant Coating, the KF Nano-X MRC UV Filter 77mm delivers pristine clarity while safeguarding your lens from ultraviolet haze, scratches, water, and oil. Its ultra-slim 3.3mm aviation aluminum frame prevents vignetting on wide-angle lenses, and the double-threaded design allows stacking or attaching a lens cap without compromise.

Overview

Engineered for photographers who demand optical purity, this 77mm UV filter uses premium Japanese AGC optical glass to block UV light below 390nm, reducing atmospheric haze and improving contrast in outdoor scenes. The Nano-X MRC coating—14 layers on each side—provides hydrophobic, oleophobic, and anti-reflective properties, making the filter easy to clean and resistant to flare and ghosting. The frame is crafted from aviation aluminum alloy, offering a robust yet lightweight build that withstands daily use.

What stands out

• Ultra-slim 3.3mm frame minimizes vignetting on wide-angle and full-frame lenses.
• Double-threaded design permits stacking additional filters or mounting a lens cap.
• 28-layer Nano-X MRC coating repels water, oil, and dust while reducing reflections.
• High light transmission (>99.6%) preserves image sharpness and colour fidelity.
• Scratch-resistant surface ensures long-term durability in challenging environments.
