Also termed a normal lens, a standard lens is a fixed focal length (non-zoom) lens that sees a scene in more or less the same proportions and perspective as does the human eye. A standard lens is neither a wide-angle (short) nor a telephoto (long) lens. A 35mm film camera s standard lens would be a 50 to 60mm lens, with a 55mm lens commonly accepted as representative. See Lens selection for info on standard and other lenses.Photo Tips
