The Canon 58mm UV filter is a multi-purpose, fine-weather filter that is designed to optimize your photography experience. Used by many photographers to protect the front element of their lens from abrasions, dust, and moisture.UV filters, absorb ultraviolet rays that often make outdoor photographs hazy and indistinct. They should be constantly fitted to a lens to provide improved clarity and color balance, as well as to provide additional protection to your lens. UV filters are perfect for digital photography and traditional 35mm SLR applications, including black and white photography.
