UV Protection Filter for Sony FE 100-400mm F4.5-5.6 GM OSS — UV-Absorbing, Optically Neutral (1x / +0 stop) Front-Element Protection

Compatible with Sony FE 100-400mm F4.5-5.6 GM OSS. This UV-absorbing filter is made to cut the haze caused by ultraviolet light—especially noticeable at high elevations, near the ocean, or on snowy terrain—reducing the bluish cast of daylight so outdoor images show more natural color and improved clarity. The glass is optically neutral with a 1x filter factor (+0 stop), so it does not change exposure, contrast, or color balance; your photos retain full sharpness, detail, and accurate tones while benefiting from UV reduction. Designed for everyday use, the filter acts as a protective barrier that can stay on the lens continuously to guard the front element from scratches, dust, dirt, water spots, fingerprints and incidental knocks or drops, helping extend the service life of your lens.
