A camera lens comprises a first lens (E1) having a positive refraction power and an object side surface of which is a convex surface, a second lens (E2) having negative refraction power and a third lens (E3) having a positive refraction power from an object side to an image side in sequence, the first lens. The camera lens meets a relational expression: tan(HFOV) > 0.74; TTL/ImgH < 1.7; and 0.6 < f1/f < 0.8 and - 1.3 < f1/f2 < -0.8. The HFOV is half of a view field angle of the camera lens, the TTL is a total length of the lens of the camera lens, the ImgH is half of a diameter of an effective pixel region of the camera lens on an imaging surface, the f1 is a focal length of the first lens (E1), the f2 is a focal length of the second lens (E2) and the f is an effective focal length of the camera lens. |
