Digital Nc Camera Accessories UV Filter | sku-17714869264

Digital Nc Camera Accessories UV filter in Black, sku-17714869264, UPC 743627202807, is made for the Pentax smc FA 645 400mm f/5.6 ED IF lens. It absorbs UV radiation that can cause haze, low contrast and a blue cast, particularly at high altitudes, near the sea or on snow. Its 1x filter factor adds +0 stop, so the listing says it does not change exposure, contrast or color balance.

The filter can stay on the lens to help protect its front element from scratches, dust, dirt, water spots, fingerprints, contact, bumps, drops and abrasions.
