A lens is part of the optical system that determines how the three-dimensional world is projected onto a two-dimensional imaging plane. Its focal length affects the angle of view and magnification, while its optical design influences characteristics such as distortion, chromatic aberration, vignetting, and the rendering of out-of-focus areas.
