Title
(EN) Camera shooting optical lens
(ZH) 摄像光学镜头
Abstract
(EN)
The invention relates to the field of optical lenses, and discloses a camera shooting optical lens. The camera shooting optical lens comprises a first lens, a second lens, a third lens, a fourth lens,a fifth lens, a sixth lens and a seventh lens in order from the object side to the image side. The following relation formulas are met: 1.51 <= f1/f <= 2.50, 1.70 <= n1 <= 2.20, -10.00 <= (R13+R14)/(R13-R14) <=10.00, and 1.70 <= n4 <= 2.20. The camera shooting optical lens achieves low TTL while achieving high imaging performance.
