UV Protector Filter for Pentax HD PENTAX-DA645 28-45mm f/4.5 ED AW SR — 1x (+0) UV Filter, Reduces Bluish Daylight Cast & Protects Lens

Compatible with the Pentax HD PENTAX-DA645 28-45mm f/4.5 ED AW SR lens, this UV protector is built to improve outdoor images and shield your front element. It selectively blocks ultraviolet rays that can introduce haze and a bluish tint—an effect that’s most noticeable at high elevations, by the sea, or on snowy terrain—so photos show more natural tones and clearer detail in challenging daylight conditions. Optical performance is maintained thanks to an optically neutral design and a 1x filter factor (+0 stop); the filter does not alter exposure, contrast, color balance, or image sharpness. Beyond image correction, the filter doubles as a durable protective layer that can remain mounted continuously. It helps guard the lens from scratches, dust, dirt, water spots, and fingerprints, and offers added protection against accidental contact, drops, bumps, and abrasions—helping preserve your lens over time.
