UV Protection Filter for Pentax HD Pentax-D FA Macro 100mm f/2.8 ED AW — Optically Neutral 1x (+0) UV Filter, Reduces Bluish Cast & Protects Lens

Made to fit the Pentax HD Pentax-D FA Macro 100mm f/2.8 ED AW, this UV protection filter blocks ultraviolet light that can produce hazy, low-contrast results — a problem common at high elevations, by the sea, or in snowy environments. By cutting UV, it lessens the bluish cast of daylight so images show more natural tones and improved clarity in a range of outdoor lighting situations. The filter is optically neutral and clear with a 1x filter factor ( +0 stop ), so it does not alter exposure, contrast, or color balance; your photos keep their full sharpness, fine detail, and true-to-life color while benefiting from UV reduction. Intended for everyday use, the filter also serves as a permanent protective layer for the front element: it guards against scratches, dust, dirt, water spots, fingerprints, and accidental contact, and provides extra defense against minor drops, bumps, or abrasions to help prolong the life of your lens.
