UV Protection Filter for Pentax HD PENTAX-D FA* 85mm f/1.4 ED SDM AW Lens — UV-Blocking, Optically Neutral 1x (+0) Filter; Scratch & Dust Guard

Made specifically for the Pentax HD PENTAX-D FA* 85mm f/1.4 ED SDM AW lens, this UV filter improves outdoor shooting by filtering ultraviolet radiation that can produce hazy, low-contrast images. It is especially helpful at high altitudes, along coastlines, or in snowy environments where UV is strong, cutting the bluish cast of daylight so colors appear more natural and overall image clarity is increased under various lighting conditions. The filter is optically neutral and has a 1x filter factor (+0 stop), so it does not change exposure, contrast, or color balance — your photos keep full sharpness, fine detail, and true-to-life tones. Designed to stay on the lens during regular use, it serves as a protective barrier against scratches, dust, dirt, water spots, fingerprints and accidental contact, while adding a measure of defense against drops, bumps and abrasions to help prolong the life of your lens.
