NiSi Ultra Slim Pro UNC UV Filter (Brass Ring) absorbs Ultraviolet Light to reduce haze and remove the blueish cast in daytime images. It assures high transmittance at 99.3% and a highly smooth surface avoids unnecessary reflection.
The frame is constructed from Brass using highly accurate brass milling. The NiSi Ultra Slim Pro UNC UV Filter has an exclusive Nano coating that makes the filter repellant from dust, oil, and water.
The UV filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.
