Abstract
(EN)
A photographing optical lens (10). The photographing 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), and a sixth lens (L6); the second lens (L2) has a negative refractive power, the third lens (L3) has a negative refractive power; and the following relational expressions are satisfied: 1.10 ≤ f1/f ≤ 3.00; -25.00 ≤ R9/d9 ≤ -10.00. The photographing optical lens (10) has a low TTL while having high imaging performance.
(FR)
Objectif photographique (10). Objectif photographique (10) comprenant dans l'ordre, du côté objet au 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) possédant une réfringence négative, la troisième lentille (L3) possédant une réfringence négative; et les expressions relationnelles suivantes étant satisfaites : 1,10 ≤ F1/f ≤ 3,00; -25,00 ≤ R9/d9 ≤ -10,00 l'objectif photographique (10) posséde une faible TTL tout en ayant une performance d'imagerie élevée.
