CAMERA LENS

WIPO Patent Application WO/2017/113557

A1

Disclosed is a camera lens. The camera lens comprises, from an object-side to an image-side and in sequence of: a first lens (L1) having a positive refractive power; a second lens (L2) having a negative refractive power, an object-side surface (S3) of the second lens being a convex surface, and an image-side surface (S4) of the second lens being a concave surface; a third lens (L3) having a positive refractive power; a fourth lens (L4) having a refractive power, an object-side surface (S7) of the fourth lens being a concave surface, and an image-side surface (S8) of the fourth lens being a convex surface; a fifth lens (L5) having a refractive power, an object-side surface (S9) of the fifth lens being a convex surface and an image-side surface (S10) of the fifth lens being a convex surface; and a sixth lens (L6) having a negative refractive power. The total number of the lenses having a refractive power in the camera lens is six. The camera lens meets requirements of: ｜f／f3｜＋｜f／f6｜＜1.0；and TTL／ImgH＜1.46; wherein f3 is an effective focal length of the third lens; f6 is an effective focal length of the sixth lens; f is an effective focal length of the camera lens, and TTL is an axial distance from an object-side surface of the first lens to an image plane; ImgH is one half of a diagonal line length of an active pixel area on the image plane. The camera lens can improve imaging quality and maintain miniaturization.
