Abstract[English]
A photographing optical lens (10, 20, 30, 40). The photographing optical lens comprises seven lenses, the seven lenses successively comprising, from an object side to an image side: a first lens (L1) having negative refractive power, a second lens (L2) having negative refractive power, a third lens (L3) having positive refractive power, a fourth lens (L4) having positive refractive power, a fifth lens (L5) having positive refractive power, a sixth lens (L6) having negative refractive power, and a seventh lens (L7) having positive refractive power; the photographing optical lens (10, 20, 30, 40) satisfies the following relational expressions: -1.30≤f1/f≤-1.00; 0.02≤d4/TTL≤0.06; n2≥1.70; and 0.10≤BFL/TTL≤0.30. The photographing optical lens (10, 20, 30, 40) can satisfy the design requirements of large aperture and wide angle.[French]
L'invention concerne un lentille optique photographique (10, 20, 30, 40). La lentille optique photographique comprend sept lentilles, les sept lentilles comprenant successivement, d'un côté objet à un côté image : une première lentille (L1) ayant une réfringence négative, une deuxième lentille (L2) ayant une réfringence négative, une troisième lentille (L3) ayant une réfringence positive, une quatrième lentille (L4) ayant une réfringence positive, une cinquième lentille (L5) ayant une réfringence positive, une sixième lentille (L6) ayant une réfringence négative, et une septième lentille (L7) ayant une réfringence positive ; la lentille optique photographique (10, 20, 30, 40) satisfait les expressions relationnelles suivantes : -1,30≤f1/f≤-1,00 ; 0,02≤d4/TTL≤0,06 ; n2≥1,70 ; et 0,10≤BFL/TTL≤0,30. La lentille optique photographique (10,20,30, 40) peut satisfaire aux exigences de conception de grande ouverture et de grand angle.[Chinese]
