NiSi NIR-UV395-49 49mm SMC UV Lens Filter Protector

The NiSi NIR-UV395-49 is a 49mm UV filter built around high-quality optical glass with a 395nm UV cutoff, designed to block ultraviolet light that can cause haze and subtle color shifts in outdoor photography. With 98.9% visible light transmittance, the filter provides lens protection without introducing noticeable exposure changes or image softness. The multi-layer SMC (Super Multi Coating) applied to both surfaces of the glass reduces internal reflections and flare, helping maintain contrast and color accuracy even when shooting toward bright light sources.

The filter's ultra-thin aluminum frame measures just 5.2mm, keeping it low-profile enough to avoid vignetting on wide-angle lenses — a common issue with thicker UV filters. A waterproof nano coating adds practical durability, repelling water droplets, oil, and fingerprints so the glass stays cleaner during extended shoots. For photographers who want full-time lens protection without compromising optical performance, the NiSi 49mm SMC UV filter is a straightforward choice that balances build quality, coating technology, and a slim form factor.
