Problems solved by technology

However, ultra-wide-angle lenses usually have a large size, making them unsuitable for use in various types of portable electronic devices that are increasingly miniaturized
In addition, most of the current ultra-wide-angle lenses still have the problems of low pixels and low relative illumination, which makes the shooting picture not uniform enough to provide better images

Abstract

The invention discloses a camera lens. The camera lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side along an optical axis, wherein the first lens has negative focal power, and the image side surface of the first lens is a concave surface; the second lens has negative focal power, the object sidesurface is a convex surface, and the image side surface is a concave surface; the third lens has positive focal power, and the image side surface of the third lens is a convex surface; the fourth lenshas focal power; the fifth lens has focal power; and the sixth lens has focal power. The on-axis distance SAG12 from the intersection point of the image side surface of the first lens and the opticalaxis to the vertex of the maximum effective half aperture of the image side surface of the first lens and the center thickness CT1 of the first lens on the optical axis satisfy 1<SAG12 / CT1<1.7.

Description

[0001] Divisional Application Statement [0002] This application is a divisional application of the Chinese invention patent application submitted on November 12, 2018. technical field [0003] The present application relates to a camera lens, and more particularly, to a camera lens including six lenses. Background technique [0004] With the ever-changing market demand, ultra-wide-angle lenses are increasingly used in automotive, monitoring, virtual reality and other fields. However, ultra-wide-angle lenses usually have a relatively large size, making it impossible to apply to various portable electronic devices that are increasingly miniaturized. In addition, most of the current ultra-wide-angle lenses still have the problems of low pixels and low relative illumination, which makes the shooting picture not uniform enough to provide better images. Contents of the invention [0005] The present application provides an ultra-wide-angle camera lens applicable to portable ...
