UV Protection Filter for Canon EF 100-400mm f/4.5-5.6L IS II USM — Optically Neutral 1x (+0 Stop) Shield Against UV, Dust & Scratches

Made specifically for the Canon EF 100-400mm f/4.5-5.6L IS II USM, this UV filter absorbs ultraviolet radiation that can cause hazy, low-contrast photos. It minimizes the bluish cast commonly seen in daylight—especially at high altitudes, by the ocean, or in snowy environments—so images render with more natural tones and clearer detail. Optically neutral performance: the filter has a clear, neutral design with a 1x filter factor (+0 stop), so it does not change exposure, contrast, or color balance. Your shots keep full sharpness, fine detail, and accurate colors while benefiting from UV reduction. Everyday protective barrier: intended to stay mounted on your lens, the filter guards the front element from dust, dirt, water spots, and fingerprints, and helps prevent scratches and accidental contact. It also provides added defense against bumps, drops, and abrasions, helping preserve the condition and longevity of your lens investment.
