NiSi 37mm Air UV Protection Filter with 99.9% Peak Transmission – 48 Multi-Layer

The NiSi Air UV Protection Filter combines exceptional optical clarity with reliable lens protection, featuring 99.9% peak light transmission achieved through NiSi’s advanced ULRC (Ultra Low Reflective Coating) technology. This premium 37mm circular filter features a sophisticated 48-layer nano-coating that resists scratches, stains, water, and oil, whilst maintaining crystal-clear optics even with high-resolution 100-megapixel cameras. With only 0.1% reflectivity, it minimises unwanted lens flares and reflections, making it an invisible protective barrier between your lens and the elements. The lightweight brass frame with knurled edges prevents vignetting on wide-angle lenses and facilitates easy installation and removal.
