The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length ,Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens. ... The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of ,The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters (e.g., 28 mm, 50 mm, or 100 mm).
