Abstract
(EN)
Disclosed is a photographic optical lens, sequentially comprising, from an object side to an image side, an aperture (S1), a first lens (L1) having a positive refractive power, a second lens (L2) having a negative refractive power, a third lens (L3) having a positive refractive power, a fourth lens (L4) having a negative refractive power, a fifth lens (L5) having a positive refractive power, and a sixth lens (L6) having a negative refractive power, wherein the focal distance of the photographic optical lens is f, the focal distance of the second lens (L2) is f2, the radius of the curvature of the object side surface of the third lens (L3) is R5, and the radius of the curvature of the image side surface of the third lens (L3) is R6, satisfying the following relational expressions: ‑2.50 ≤ (R5+R6)/(R5‑R6) ≤ ‑1.00, and ‑7.00 ≤ (f2/f) ≤ ‑3.50. The photographic optical lens satisfies the large-aperture, ultra-thin and wide-angle design requirements, while also having a good optical performance.
