Product DescriptionVivitar Filters are manufactured from high-quality solid optical materials. Each individual filter is heat-treated to avoid any rare movement or distortion. Our UV filters remove and absorb ultra violet rays, giving sharper contrast to your digital images. Our Ultra Violet filters minimize the bluish cast sometimes found under daylight conditions. These filters will render your photos clearer, sharper and with more contrast. For those who enjoy outdoor photography, especially distant vistas, a UV filter can produce a more distinct image by removing much of the color aberration normally associated with atmospheric haze.
