Abstract
(EN)
Disclosed is a photographic optical lens (10). The photographic optical lens (10) sequentially comprises, from an object side to an image side, 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), wherein the following relationship expressions are satisfied: 1.51 ≤ (f1/f) ≤ 2.50, 1.70 ≤ n6 ≤ 2.20, -2.00 ≤ (f3/f4) ≤ 2.00, 0.00 ≤ (R13+R14)/(R13-R14) ≤ 10.00, and 0.015 ≤ (d11/TTL) ≤ 0.200. The photographic optical lens (10) can achieve a low TTL while achieving a high imaging performance.

L'invention concerne une lentille optique photographique (10). La lentille optique photographique (10) comprend séquentiellement, d'un côté objet à un côté image, 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), les expressions de relation suivantes étant satisfaites : 1,51 ≤ (f1/f) ≤ 2,50, 1,70 ≤ n6 ≤ 2,20, -2,00 ≤ (f3/f4) ≤ 2,00, 0,00 ≤ (R13+R14)/ (R13-R14) ≤ 10,00, et 0,015 ≤ (d11/TTL) ≤ 0,200. La lentille optique photographique (10) peut atteindre une faible TTL tout en obtenant une performance d'imagerie élevée.
