Title
(EN) Optical lens for camera shooting
(ZH) 摄像光学镜头
Abstract
(EN)
The invention relates to the field of optical lenses, and discloses an optical lens for camera shooting. The optical lens for camera shooting comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from the object side to the image side in sequence, wherein the second lens has positive refractive power, and the third lens has positive refractive power; andthe following relational expressions are satisfied: 1.40<=f1/f3<=5.00, and 2.50<=R5/R6<=6.00. The optical lens for camera shooting can achieve low TTL while acquiring high imaging performance.
