UV Protector Filter for Pentax-D FA 645 55mm f/2.8 AL[IF] SDM AW Lens — Optical UV Absorber, 1x Filter Factor (+0 stop), Scratch & Dust Protection

Made specifically for the Pentax-D FA 645 55mm f/2.8 AL[IF] SDM AW Lens, this UV protector absorbs ultraviolet light that can produce hazy, low-contrast results—especially at high altitudes, along the coast, or in snowy environments. By cutting UV, it diminishes the bluish daylight cast so images show truer tones and improved clarity in a wide range of lighting conditions. The filter is optically neutral and crystal clear, with a 1x filter factor (+0 stop), so it leaves exposure, contrast, and color balance unchanged while preserving full sharpness and detail. Designed for everyday use, it serves as a protective barrier that can remain on the lens: it helps prevent scratches, dust, dirt, water spots, fingerprints and accidental contact with the front lens element, and adds extra defense against drops, bumps or abrasions to help extend the life of your lens.
