Abstract
(EN)
Disclosed is a photographic optical lens (10). The photographic optical lens (10) sequentially includes, 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), and a sixth lens (L6), wherein the second lens (L2) has a positive refractive power, the third lens (L3) has a positive refractive power, and the following relationships are satisfied: 1.40 ≤ f1/f3 ≤ 5.00, and 2.50 ≤ R5/R6 ≤ 6.00. The photographic optical lens (10) can obtain low TTL and also obtain 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), et une sixième lentille (L6), la deuxième lentille (L2) ayant une réfringence positive, la troisième lentille (L3) ayant une réfringence positive, et les relations suivantes étant satisfaites : 1,40 ≤ f1/f3 ≤ 5,00, et 2,50 ≤ R5/R6 ≤ 6,00. La lentille optique photographique (10) peut obtenir une TTL faible et obtenir également une performance d'imagerie élevée.
