UV Protective Filter for Pentax HD FA 50mm f/1.4 SDM AW — UV Absorption, Bluish-Cast Reduction & Lens Protection (1x / +0 stop)

Fits Pentax HD FA 50mm f/1.4 SDM AW. This UV filter is engineered to absorb ultraviolet light that can produce hazy, low-contrast results—an effect most noticeable at high elevations, by the sea, or on snowy terrain. By cutting UV, it helps minimize the bluish cast of daylight so images show truer tones and better clarity under a range of outdoor conditions.

Optically neutral with a 1x filter factor (+0 stop), it does not alter exposure, contrast, or color balance, preserving sharpness, detail, and accurate colors while still providing UV reduction. Intended for daily use as a front-line safeguard, the filter shields the lens from scratches, dust, dirt, water spots, and fingerprints, and offers added protection against accidental contact, drops, bumps, or abrasions.

It can be left mounted on the lens continually for ongoing protection without affecting image quality.
