NiSi Filter UV SMC L395 49mm – Ultra-thin 3 mm UV-cut filter for wide-angle lenses

The NiSi Filter UV SMC L395 49mm blocks ultraviolet light below 395 nm while maintaining high image clarity. It uses high-quality Japanese optical glass and a double-sided multi-coating to preserve transmittance and reduce reflections. The filter’s ultra-thin aluminum frame measures only 3 mm, which makes it suitable for use on wide-angle lenses and helps prevent vignetting and unwanted reflections.
