A lens with a short focal length. Lenses of this type do not cover the diagonal of the negative. They produce a smaller image, at the same distance, than those yielded by normal or long-focus lenses but cover a greater part of that image. 1, record 1, English, - short%2Dfocus%20lens

Designations like "wide angle" or "narrow angle" are not necessarily synonymous with "short focus" and "long focus", as the latter terms refer to the focal length of the lens relative to the picture format. 3, record 1, English, - short%2Dfocus%20lens

Pour une longueur focale donnée, l'objet photographié a une dimension de reproduction constante, quel que soit le format, et c'est seulement le champ de l'image qui s'élargit en même temps que grandit ce dernier. Autrement dit, pour une distance focale déterminée, l'objet photographié avec des appareils de formats différents aura à une distance constante une dimension constante; seule l'étendue du paysage qui l'entoure variera. On emploie couramment les expressions suivantes: objectif de courte longueur focale, de grande longueur focale, etc. 1, record 1, French, - objectif%20de%20courte%20longueur%20focale

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 4, 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 4, French, - objectif%20%C3%A0%20longue%20focale
