Title (EN) TELEPHOTO LENS AND RECORDING DEVICE
(FR) TÉLÉOBJECTIF ET DISPOSITIF D'ENREGISTREMENT
(ZH) 摄远镜头以及摄像装置
Abstract:
(EN) A telephoto lens, the telephoto lens being provided with a first lens (E1), a second lens (E2), a third lens (E3), a fourth lens (E4) and at least one subsequent lens sequentially from an object side to an image side along an optical axis. The first lens (E1) has positive focal power, and an object-side surface (S1) thereof is a convex surface; an axis distance TTL from the object-side surface (S1) to an imaging surface (S13) of the first lens (E1) and a total effective focal length f of the telephoto lens meet a condition therebetween of: TTL/f≤1.0; the fourth lens (E4) has positive focal power; and a condition is met between the effective focal length f1 of the first lens (E1), the effective focal length f4 of the fourth lens (E4) and the total effective focal length f, the condition being: 1<|f/f1|+|f/f4|≤2.7.
(FR) La présente invention concerne un téléobjectif, le téléobjectif étant pourvu d'une première lentille (E1), d'une deuxième lentille (E2), d'une troisième lentille (E3), d'une quatrième lentille (E4) et au moins d'une lentille ultérieure séquentiellement d'un côté objet au côté image le long d'un axe optique. La première lentille (E1) a une puissance focale positive, et une surface côté objet (S1) associée est une surface convexe ; une distance d'axe TTL allant de la surface côté objet (S1) à une surface d'imagerie (S13) de la première lentille (E1) et une longueur focale effective totale f du téléobjectif satisfont à une condition entre elles : TTL/f ≤ 1,0 ; la quatrième lentille (E4) a une puissance focale positive ; et une condition est satisfaite entre la longueur focale effective f1 de la première lentille (E1), la longueur focale effective f4 de la quatrième lentille (E4) et la longueur focale effective totale f, la condition étant : 1<|f/f1|+|f/f4|≤2,7.
(ZH) 一种摄远镜头,摄远镜头沿着光轴从物侧至像侧依次设置有第一透镜(E1)、第二透镜(E2)、第三透镜(E3)、第四透镜(E4)和至少一个后续透镜,第一透镜(E1)具有正光焦度,其物侧面(S1)为凸面,并且第一透镜(E1)的物侧面(S1)至成像面(S13)的轴上距离TTL与摄远镜头的总有效焦距f之间满足:TTL/f≤1.0,以及第四透镜(E4)具有正光焦度,第一透镜(E1)的有效焦距f1、第四透镜(E4)的有效焦距f4与总有效焦距f之间满足:1<|f/f1|+|f/f4|≤2.7。
