CAMERA LENS ASSEMBLY |
| 摘要 |
Provided is a camera lens assembly, including a first lens, a second leas, a third leas, a fourth lens sad a filth lens from an object side of the camera lens assembly to an image side of the camera lens assembly in turn. The first lens is of a positive focal power, an object side surface of the first lens is convex and an image side surface of the first is concave; the second lens is of a focal power; the third lens is of a negative focal power; the fourth lens is of a positive focal power, an image side surface of the fourth lens is convex; the fifth lens is of a negative focal power, and at least one inflection point is present in at least one of object and image side surfaces of the fifth lens. The camera lens assembly meets the following formulas: TTL/2Y≦0.7; and −0.7<f/f3<−0.3. |

1. A camera lens assembly, comprising a first lens, a second lens, a third lens, a fourth leas and a fifth lens from an object side of the camera lens assembly to an image side of the camera lens assembly in turn, wherein
the first lens is of a positive focal power, an object side surface of the first lens is convex and an image side surface of the first is concave; the second lens is of a focal power; the third lens is of a negative focal power; the fourth lens is of a positive focal power, an image side surface of the fourth lens is convex; the fifth lens is of a negative focal power, and at least one inflection point is present in at least one of object and image side surfaces of the fifth lens; the camera lens assembly comprises: an aperture stop arranged between a subject and the second lens; the camera lens assembly meets the following formulas:
TTL/2Y≦0.7; and0.7<f/f3<−0.3, wherein TTL is a total length of the camera lens assembly, Y equals to half-length of a diagonal of an effective pixel region at an imaging side surface, f represents an effective focal length of the camera lens assembly, and B represents an effective focal length of the third lens. |
