Abstract

The invention provides a camera lens. The camera lens comprises a first lens with focal power; the second lens has focal power, and the focal length of the second lens is variable; the surface, close to the image side, of the third lens is a convex surface; the fourth lens has focal power; the surface, close to the object side, of the fifth lens is a concave surface, and the surface, close to the image side, of the fifth lens is a convex surface; the sixth lens has positive focal power, and the surface, close to the object side, of the sixth lens is a concave surface; a seventh lens with focal power; the eighth lens has focal power; the effective focal length f of the pick-up lens and the effective focal length f1 of the first lens meet the following condition: 0 lt; | f/f1 | lt; 3; half ImgH of the diagonal length of an effective pixel area on the imaging surface of the camera lens meets ImgHgt; 5. The problem that in the prior art, a camera lens is large in size is solved.

Description

technical field [0001] The present invention relates to the technical field of optical imaging equipment, in particular to a camera lens. Background technique [0002] With the popularization of mobile phones, there are more and more daily needs for mobile phone shooting, and the requirements for shooting of camera lenses are getting higher and higher. At present, the camera lenses on mobile phones all have the function of zooming. It uses two lenses, and then drives the lens to move through a motor to change the distance between the two lenses to achieve zooming. However, in this case, the camera lens becomes bulky. [0003] That is to say, the camera lens in the prior art has the problem of large volume. Contents of the invention [0004] The main purpose of the present invention is to provide a camera lens to solve the problem of large size of the camera lens in the prior art. [0005] In order to achieve the above object, according to one aspect of the present inven...
