UV Protective Filter for Pentax HD Pentax DA* 11-18mm f/2.8 ED DC AW Lens — UV Absorbing, Neutral 1x (+0) Factor, Dust & Scratch Protection

Made specifically for the Pentax HD Pentax DA* 11-18mm f/2.8 ED DC AW Lens. Improves outdoor results by absorbing ultraviolet rays that can produce hazy, low-contrast images—an effect that’s most noticeable at high elevations, along the coast, or in snowy environments. By cutting UV-related blue casts in daylight, the filter helps deliver more natural color rendition and clearer images in a variety of lighting situations. Optically neutral design with a 1x filter factor (+0 stop) means the filter does not alter exposure, contrast, or color balance. You keep full sharpness, fine detail, and true-to-life color accuracy while benefiting from reduced ultraviolet influence on your photos. Built for everyday protection: leave it mounted to guard the front element from scratches, dust, dirt, water spots, fingerprints, and accidental contact. It also provides an additional buffer against bumps, drops, and abrasions, helping to protect and extend the usable life of your lens investment.
