The extent of a scene that a camera lens can capture, usually measured in degrees. Angle of view varies depending on the lens focal length and the size of the camera's sensor or film format. Wide-angle lenses have a larger angle of view, capturing more of the scene, while telephoto lenses have a narrower angle of view, isolating distant subjects. Understanding angle of view is essential for composing images, framing subjects, and selecting the right lens for landscape, architectural, or portrait photography.
