Abstract

Provided is a camera lens, including a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side of the camera lens to an image side of the camera lens in turn. The first lens is of a positive focal power, an object side surface of the first lens is convex; the second lens is of a negative focal power; the third lens is of a negative focal power, an object side surface of the third lens is concave; the fourth lens is of a positive focal power; the fifth lens is of a positive focal power, an image side surface of the fifth lens is convex; the sixth lens is of a negative focal power, an image side surface of the sixth lens is concave; and the camera lens meets the following formula: 0<f/f4<0.8; 0<T12/T23<0.14.
