UV Protective Filter — Compatible with Pentax SMCP-DA* 300mm f/4 ED (IF) SDM | Optically Neutral (1x filter factor (+0 stop)) Lens Protector

Compatible with the Pentax SMCP-DA* 300mm f/4 ED (IF) SDM Lens. This UV filter is built to absorb harmful ultraviolet rays that can produce hazy, low-contrast images — a common issue at high altitudes, near the ocean, or in snowy environments. By reducing the bluish cast of daylight, it helps deliver more natural color tones and clearer outdoor photos in a wide range of lighting conditions. Optically neutral performance: the filter features a clear, non-color-shifting design with a 1x filter factor (+0 stop). It does not change exposure, contrast, or color balance, so image sharpness, fine detail, and accurate color rendition are preserved while you benefit from UV reduction. Everyday front-element protection: leave the filter mounted for constant protection against scratches, dust, dirt, water spots, fingerprints, and accidental contact with the front lens element. It also provides an added layer of defense against drops, bumps, and abrasions, helping to prolong the service life of your lens investment.
