UV Protection Filter for Pentax smc FA 645 80-160mm f/4.5 Lens — Absorbs UV, Reduces Blue Cast, Everyday Lens Guard

Compatible with the Pentax smc FA 645 80-160mm f/4.5 Lens. This UV filter absorbs harmful ultraviolet radiation that can introduce haze and lower contrast—especially noticeable at high elevations, by the sea, or on snowy terrain—helping reduce the bluish cast of daylight so images appear with more natural tones and improved clarity. The filter features a clear, optically neutral construction with a 1x filter factor (+0 stop), so it does not change exposure, contrast, or color balance; sharpness, fine detail, and true color accuracy are preserved while you benefit from UV reduction. Intended for regular use, it serves as a protective barrier for the front element: guards against scratches, dust, dirt, water spots, and fingerprints, and offers additional protection from accidental contact, drops, bumps, or abrasions—extending the usable life of your lens without impacting image quality.
