A long-focus lens gives a high resolution image over quite a narrow field of view. Its long focal length means that the main lens elements must be mounted at the front of a long tube to be at a sufficient distance from the film to form a sharp image. 2, record 1, English, - long%20focal%20length%20lens

Objectifs de longue focale - Leur angle de champ est inférieur ou très inférieur à celui de l'objectif normal. [...] Un objectif de longue focale donne une image dont la perspective - la convergence naturelle des lignes parallèles du sujet - semble moins forte. Les plans du sujet, normalement étagés en profondeur - un paysage, par exemple - paraissent se confondre les uns avec les autres. 5, record 1, French, - objectif%20%C3%A0%20longue%20focale
