UV Protector Filter for IRIX 15mm f/2.4 Firefly K — Optically Neutral 1x (+0 stop), Reduces Blue Daylight Cast & Protects Lens

Made for the IRIX 15mm f/2.4 Firefly K, this UV protector is engineered to absorb ultraviolet light that can cause hazy, low-contrast results — a problem often encountered at high altitudes, near the sea, or in snowy environments. By cutting UV transmission, it diminishes the bluish cast of daylight so images show more natural tones and better overall clarity in a variety of outdoor conditions. The filter uses a clear, optically neutral construction with a 1x filter factor (+0 stop), so it does not change exposure, contrast, or color balance; sharpness, fine detail, and true color fidelity are preserved. Designed for daily use, the filter remains convenient to leave mounted on the lens, acting as a first line of defense against scratches, dust, dirt, water spots, and fingerprints or accidental contact with the front element. It also provides added protection from drops, bumps, and abrasions, helping extend the usable life of your lens.
