A camera lens, sequentially comprising: a first lens (E1) having positive refractive power, an object side face (S1) of the first lens (E1) being a convex surface, and an image side face of the first lens(E1) being a concave surface; a second lens (E2) having refractive power; a third lens (E3) having negative refractive power; a fourth lens (E4) having positive refractive power, an image side face (S8) of the fourth lens (E4) being a convex surface; and a fifth lens (E5) having negative refractive power, and at least one of an object side face (S9) and an image side face (S10) of the fifth lens (E5) having at least one inflexion point. The camera lens meets the following relational expressions: TTL/2Y≦0.7; -0.7＜f/f3＜-0.3, wherein, TTL is a total length of the camera lens, Y is half of a length of a diagonal line of an effective pixel region on an imaging plane (S13), f is an effective focal length of the camera lens, and f3 is an effective focal length of the third lens (E3). By being configured as above, the camera lens has a relatively large field angle and a characteristic of being ultrathin, and also has good imaging quality. |
