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 seven lenses, namely a first lens, a second lens, a thirdlens, a fourth lens, a fifth lens, a sixth lens and a seventh lens in sequence from an object side to an image side; at least one of the first to seventh lenses includes a free-form surface; the focal length of the whole camera shooting optical lens is f; the focal length of the fourth lens is f4; the on-axis thickness of the third lens is d5; the on-axis distance from the image side face of thethird lens to the object side face of the fourth lens is d6, and the following relational expressions are met:-4.50 < = f4/f < =-2.00 and 0.65 < = d5/d6 < = 19.50. The camera shooting optical lens provided by the invention has good optical performance and meets the design requirements of ultra-thinness, wide angle and large aperture.
(ZH) 本发明涉及光学镜头领域,公开了一种摄像光学镜头,该摄像光学镜头共包括七片透镜,七片所述透镜自物侧至像侧依序为:第一透镜,第二透镜,第三透镜,第四透镜,第五透镜,第六透镜,以及第七透镜;第一透镜至第七透镜中的至少一个含自由曲面,摄像光学镜头整体的焦距为f,第四透镜的焦距为f4,第三透镜的轴上厚度为d5,第三透镜的像侧面到第四透镜的物侧面的轴上距离为d6,且满足下列关系式:‑4.50≤f4/f≤‑2.00;0.65≤d5/d6≤19.50。本发明提供的摄像光学镜头具有良好光学性能的同时,满足超薄化、广角化、大光圈的设计要求。
