Abstract

The invention discloses an optical imaging camera lens. The optical imaging camera lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens along an optical axis in sequence from an object side to an image side. The first lens has positive focal power, wherein the object side face of the first lens is a convex face, andthe image side face of the first lens is a concave face. The second lens has negative focal power, wherein the image side face of the second lens is a concave face. The third lens has focal power, wherein the object side face of the third lens is a convex face, and the image side face of the third lens is a concave face. The fourth lens has focal power, the fifth lens has focal power, and the sixth lens has focal power. The seventh lens has positive focal power, wherein the object side face of the seventh lens is a convex face. The eighth lens has negative focal power, wherein the object sideface of the eighth lens is a concave face, and the image side face of the eighth lens is a concave face. The half length ImgH of the diagonal line of an effective pixel region on an imaging face of the optical imaging camera lens is larger than 5.80 mm, and the effective focal length f7 of the seventh lens and the total effective focal length f of the optical imaging camera lens meet the conditionthat f7 / f is larger than 1.00 and smaller than 2.00.

Description

technical field [0001] The present application relates to an optical imaging lens, in particular to an optical imaging lens including eight lenses. Background technique [0002] In recent years, with the rapid development of portable electronic products such as smart phones and tablet computers, people have higher and higher requirements for imaging lenses mounted on portable electronic devices. On the one hand, people are pursuing miniaturization and thinning of portable electronic products. On the other hand, people require that the imaging lens mounted on the portable electronic device has a higher shooting definition. This requires the matching optical imaging lens to meet the requirements of miniaturization and high imaging quality at the same time. In addition, traditional imaging lenses with a small number of lenses are difficult to achieve large image area characteristics, and cannot better meet the current requirements of people for daily shooting.
