UV Protector Filter for Canon RF 135mm F1.8 L IS USM — Optically Neutral UV Blocker (1x filter factor, +0 stop) and Front-Lens Protection

Specifically built for the Canon RF 135mm F1.8 L IS USM, this UV protector absorbs ultraviolet rays that can produce hazy, low-contrast images—especially noticeable at high elevations, along coastlines, or in snowy scenes. By reducing the bluish daylight cast, it helps your photos display more natural tones and improved clarity across a variety of lighting conditions. Its clear, optically neutral construction with a 1x filter factor (+0 stop) does not alter exposure, contrast, or color balance, so your shots preserve full sharpness, fine detail, and accurate color while still benefiting from UV reduction. Designed for daily use, the filter serves as a protective barrier that can stay mounted on the lens: it guards against scratches, dust, dirt, water spots, fingerprints, and accidental contact with the front element, and provides additional protection from bumps, drops, and abrasions to help extend the service life of your lens.
