In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture"). It is also known as the focal ratio, f-ratio, or f-stop, and is very important in photography. It is a dimensionless number that is a quantitative measure of lens speed; increasing the f-number is referred to as stopping down. The f-number … Il rapporto focale, o f-stop, indicato con il simbolo ƒ (o f), indica il rapporto esistente tra lunghezza focale (F) di un obiettivo ed il diametro (D) del diaframma in cui entra la luce.
