Correlazione tra lunghezza focale, angolo e prospettiva

La lunghezza focale, misurata in millimetri, è la distanza tra il centro dell'obiettivo e il punto di messa a fuoco. Influisce sull'angolo e la prospettiva delle immagini catturate. Una lunghezza focale ridotta si traduce in un'ampia angolatura che consente di catturare immagini più ampie. Una grande lunghezza focale si traduce in un'angolatura minore che consente di catturare immagini teleobiettivo.
