UV Protection Filter for Pentax HD-DA 16-50mm f/2.8ED PLM AW Lens — Ultraviolet Absorbing, Reduces Blue Cast, Dust & Scratch Guard

Made to fit the Pentax HD-DA 16-50mm f/2.8ED PLM AW lens, this UV protector is intended for outdoor shooting where ultraviolet light can degrade image clarity. It absorbs UV radiation that often produces hazy, low-contrast results—an issue commonly seen at high elevations, by the sea, or in snowy environments—helping to minimize the bluish tint of daylight and restore more natural color tones. Optically neutral construction ensures image integrity: the filter has a 1x filter factor (+0 stop), so it does not change exposure, contrast, or color balance. You retain full sharpness, fine detail, and accurate color rendition while benefiting from reduced UV influence. Beyond image improvements, the filter serves as a durable first line of defense for your lens. Keep it mounted permanently to shield the front element from scratches, dust, dirt, water spots, fingerprints, and accidental contact. It also helps protect against bumps, drops, and abrasions, contributing to the long-term preservation of your lens investment.
