Camera Field of View

The camera field of view is determined by the angle of view from the lens out to the scene and can be measured vertically or horizontally. Because the aspect ratio differs between formats, the more universal camera field of view is calculated along the diagonal of the scene. A shorter focal length (such as a 28mm wide angle) produces a wider picture angle, while a longer focal length (such as a 200mm tele) produces a narrower picture angle. In 35mm photography (35mm camera sensor), a 50mm lens is called a normal lens because it produces approximately the same picture angle as the human eye (about 46°).
