UV Protection Filter for IRIX 21mm f/1.4 Dragonfly K — Blocks UV, Reduces Blue Daylight Cast, Shields Against Dust & Scratches

Made specifically for the IRIX 21mm f/1.4 Dragonfly K, this UV protector absorbs ultraviolet radiation that can create hazy, low-contrast images—an effect that is especially apparent at high elevations, along the coast, or in snowy environments. By reducing the bluish cast of daylight, it helps reproduce truer colors and improved image clarity in a variety of outdoor lighting conditions. Optically neutral construction with a 1x filter factor (+0 stop) means the filter does not alter exposure, contrast, or color balance; your photos retain full sharpness, detail, and natural color accuracy. Intended for everyday use, the filter serves as a permanent front-element shield to guard against scratches, dust, dirt, water spots, fingerprints, and accidental contact. It also provides added protection from bumps and drops, helping extend the usable life of your lens.
