WebIn optics, optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device: P = 1/f. [1] High optical power corresponds to short focal length. WebMay 30, 2024 · Photographic lenses generally have a focal length of between 14mm and 600mm, although there some expensive exceptions that have shorter or longer focal lengths. The shorter the focal length, the wider the field of view. The longer the focal length, the narrower the field of view.

Without getting into an in-depth physics discussion, the focal length of a lens is an optical property of the lens. It measures the distance, in millimetres, between the optical centre of the lens and the camera’s sensor (or film plane). It is determined with the camera focused to infinity.

WebJul 1, 2024 · The focal length of the telephoto lens in its 35 mm equivalent tells you how well the smartphone can zoom in on distant subjects via optical magnification. If the ratio between the fantasy magnification and optical magnification drifts too far apart, the phone will have to perform its zoom digitally - and the picture quality will definitely suffer.
