The Hoya 49mm EVO Antistatic UV(0) Filter is a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. It is also useful as a general protective filter to leave on lenses at all times in order to reduce dust and moisture from reaching the front lens element and to provide additional protection in case of accidental impacts.
The EVO antistatic coating on this filter helps to repel dust, water, scratches, and stains, and aids in making the substrate easy to clean. Additionally, a 18-layer multicoating helps to reduce surface reflections and ghosting for maintained contrast and clarity. The optical glass filter is set within a one-piece, low-profile aluminum ring, which lessens the likelihood of vignetting if used on a wide-angle lens. The ring also features front threads for attaching additional filters or lens caps.
