UV Protector Filter Compatible with Pentax HD Pentax DA 21mm f/3.2 AL Limited Lens – Absorbs Ultraviolet Light, Reduces Bluish Cast of Daylight, Prevents Dust, Protects from Scratches

The UV Protection Filter is a general-use, optically clear filter that both improves outdoor photography and safeguards your lens investment. By absorbing ultraviolet (UV) light, it reduces the bluish haze often seen in bright daylight, at high altitudes, or near reflective water and snow. Unlike colored filters, it will not affect color balance or contrast, making it easy to use alone or combined with other filters. This filter also provides everyday protection. Once mounted, it creates a reliable shield against dust, moisture, fingerprints, and scratches—while adding a layer of defense against bumps or accidental drops. Many photographers leave it on full-time as a permanent lens protector. Built with multi-coated optical glass, it delivers sharpness, clarity, and excellent light transmission. The filter is housed in a precision aluminum frame for durability, easy threading, and long-lasting performance. Ideal for both photographers and videographers, this UV filter is a must-have accessory for keeping your images sharp and your gear safe in any environment.
