Slim Design. Designed with a slim design metal ring. The thickness of the metal ring projects only 3.5 mm past the front of the lens. Knurled front edge provide a better grip. Total thickness of the filter is only 5.5 mm.

UV filters are designed to prevent ultraviolet (UV) light from getting through. UV filters are used in photography to reduce the level of ultraviolet light that strikes the recording medium.

Historically, photographic films were mostly sensitive to UV light, which caused haziness or fogginess, and in color films a bluish hue. Therefore, as a standard, a UV (blocking) filter was used, transparent to visible light while filtering out shorter ultraviolet wavelengths. 

Many photographers and cinematographers still use UV filters as a protection for their lenses' glass and coating, due to their low cost and lack of effect on the exposure of the shot.
