camera lens

Abstract

Disclosed in the invention is a shooting lens comprising a first lens having the positive focal power, a second lens having the focal power, a third lens having the positive focal power, a fourth lens having the negative focal power, a fifth lens having the positive focal power, and a sixth lens having the negative focal power from the object side to the image side. An object side surface of the second lens is a convex surface and an image side surface of the second lens is a concave surface; an object side surface of the fourth lens is a concave surface; a part, approaching an axis, of an object side surface of the fifth lens is a convex surface and a part, approaching the axis, of the image side surface is a convex surface. The shooting lens meets the condition: f / f56 is larger than 0 and is less than or equal to 0.35, and R9 / R10 is larger than -1.7 and is less than or equal to -0.8, wherein the f expresses an effective focal length of the shooting lens, the f56 expresses a combined focal length of the fifth lens and the six lens, the R9 expresses a curvature radius of the object side surface of the fifth lens, and the R10 expresses a curvature radius of the image side surface of the fifth lens. According to the shooting lens, incident angles of all view fields can be adjusted effectively; all aberration, especially distortion, can be corrected well; and thus the imaging quality can be improved. Meanwhile, configuration of the shooting lens is compact and thus the size of the shooting lens can be effectively reduced, so that miniaturization can be kept.

Description

Technical field [0001] The present invention relates to the field of imaging technology, in particular to an imaging lens. Background technique [0002] In recent years, with the development of chip technologies such as CCD or CMOS, camera lenses have gradually developed into the fields of high pixels and miniaturization. In order to meet this trend, camera lenses used in portable electronic products are also required to be miniaturized and high imaging. performance. [0003] At present, the mainstream camera lens generally consists of five lenses, and it is difficult to meet the resolution requirements of higher pixels and higher quality. Therefore, it is necessary to increase the number of lenses. However, the increase in the number of lenses is not conducive to the miniaturization and weight reduction of the lens. Summary of the invention [0004] The embodiments of the present invention aim to solve at least one of the technical problems existing in the prior art. For this re...
