NiSi 40.5mm Pro Nano Air Protection Filter with 99.8% Peak Transmission

The NiSi 40.5mm Pro Nano Air Protection Filter combines precision optical engineering with advanced protection technology. Constructed from ultra water-white optical glass, this filter delivers 99.8% light transmittance with zero colour, exposure or contrast shift. Featuring 48 layers of double-sided multi-layer nano coating, it repels dust, oil and moisture while maintaining pristine image clarity across cinematic footage and detailed stills alike. The ultra-thin aluminium frame minimises weight and eliminates vignetting on wide-angle lenses, whilst the precisely machined knurled edge ensures secure grip for quick mounting even in field conditions.
