photographic lens

A photographic lens is a device made of glass or plastic that focuses light onto a camera's sensor or film, capturing images. It determines how much of the scene is in focus (sharpness), how bright the image appears, and the perspective or depth created. Different lenses have various focal lengths—like wide-angle for broad scenes or telephoto for distant subjects—that influence the image’s composition. Essentially, the lens is a vital tool that controls the quality, clarity, and style of your photographs by manipulating light and perspective.
