Abstract
(EN)
A photographing optical lens assembly (10). The photographing optical lens assembly (10) comprises, from an object side to an image side in the following order: a first lens (L1); a second lens (L2); a third lens (L3); a fourth lens (L4); a fifth lens (L5); a sixth lens (L6); and a seventh lens (L7). The photographing optical lens assembly (10) satisfies the following relations: 1.51 ≤ f1/f ≤ 2.50, 1.70 ≤ n1 ≤2.20, -10.00 ≤ (R13 + R14)/(R13 - R14) ≤ 10.00, 1.70 ≤ n4 ≤ 2.20. The photographing optical lens assembly (10) has high imaging performance and a short TTL.

L'invention concerne un ensemble lentille optique photographique (10). L'ensemble lentille optique photographique (10) comprend, d'un côté objet à un côté image, dans l'ordre suivant : une première lentille (L1) ; une deuxième lentille (L2) ; une troisième lentille (L3) ; une quatrième lentille (L4) ; une cinquième lentille (L5) ; une sixième lentille (L6) ; et une septième lentille (L7). L'ensemble lentille optique photographique (10) satisfait les relations suivantes : 1,51 ≤ f1/f ≤ 2,50 ; 1,70 ≤ n1 ≤ 2,20 ; -10,00 ≤ (R13 + R14)/ (R13-R14) ≤ 10,00 ; 1,70 ≤ n4 ≤ 2,20. L'ensemble lentille optique photographique (10) a une performance d'imagerie élevée et une TTL courte.
