K&F Concept Nano-X UV-HD 62mm 28-Layer MC UV Filter

K&F Concept Nano-X UV-HD 62mm Filter

The K&F Concept Nano-X UV-HD is a 62mm screw-in filter designed for DSLR camera lenses. It blocks ultraviolet rays to reduce blue haze and improve clarity while shielding the front element from shock, water, dust, scratches, oil and fingerprints. Photographers seeking a protective filter that maintains image quality will find it suitable for daily use.

28-Layer Multi-Coating and 99.6% Transmission

The filter features 28 nanometre-scale coatings on both glass surfaces, achieving 99.6% light transmission. This multi-layer design minimises reflections from the filter and surrounding surfaces to preserve true colour rendition. The coating stack also provides water-repellent, oil-resistant and scratch-resistant properties. Optical performance is limited by the physical properties of the UV absorption layer and the coating durability under heavy cleaning.

3.3mm Ultra-Slim Tempered Glass Frame

Japanese AGC optical glass is tempered to 9H hardness and rated to survive a 2m drop without damage to the lens. The frame measures only 3.3mm thick with double-sided polishing, preventing vignetting on wide-angle and telephoto lenses. The slim profile allows a lens cap to fit over the filter, though the minimal knurling may require careful grip when mounting or removing the filter in cold or wet conditions. Buyers who need a front thread for stacking additional filters or a lens hood that attaches to the filter threads cannot use this model.
