52mm High Resolution 3-piece Filter Set (UV, Fluorescent, Polarizer) - Black - for Nikon D40, D60 Multi-coated optical glass for enhanced optical resolution. FILTER UV: Protects your camera's lens from scratches, dust, dirt, moisture, and fingerprints, while reducing unwanted ulra-violet light. FILTER FD: The F-DL fluorescent light correction filter gives true-to-life color rendition by removing the harsh yellow-green cast ordinarily resulting from fluorescent bulbs. When shooting under natural light, a fluorescent filter dramatically increases color saturation of subjects. FILTER PL: Polarizers let you achieve vibrant color saturation, reduce or eliminate glare and reflections from non-metallic objects and glass surfaces, and minimize haze. The filter can be rotated to determine the amount of reflection to be removed. Includes protective carrying case. Backed by a 15 year USA warranty.
