UV Protection Filter for Pentax smc FA 645 120mm f/4 Macro Lens — Reduces Bluish Daylight Cast, Protects Front Element

Made specifically for the Pentax smc FA 645 120mm f/4 Macro Lens, this UV protector filter blocks ultraviolet light that can introduce haze and reduce contrast—particularly noticeable at high elevations, by the sea, or on snow-covered terrain. By cutting UV, it reduces the bluish daylight cast so images display more natural tones and improved clarity in a range of outdoor lighting conditions. Optically neutral and clear, the filter has a 1x filter factor (+0 stop) so it does not alter exposure, contrast, or color balance; your photos keep full sharpness, fine detail, and true color accuracy while benefiting from UV reduction. Built for everyday use as a permanent front-element safeguard, it helps guard against scratches, dust, dirt, water spots, and fingerprints, and provides extra protection against bumps, drops, and abrasions—helping extend the useful life of your lens.
