Claim 14:
15. A camera module, comprising an optical lens and an image sensor opposite to the optical lens, wherein from an object side to an image side along an optical axis, the optical lens comprises:
a first lens having a positive focal power, wherein an object side surface of the first lens is convex;
a second lens having a negative focal power;
a third lens having a negative focal power;
a fourth lens having a negative focal power;
a fifth lens having a positive focal power, wherein an object side surface of the fifth lens is convex at a paraxial region thereof, and an image side surface of the fifth lens is concave at a paraxial region thereof;
a stop disposed between the second lens and the third lens; and
a filter disposed between the fifth lens and an imaging plane;
wherein the first lens, the second lens, the third lens, the fourth lens and the fifth lens are all plastic aspherical lenses, and the optical lens satisfies expressions:

0<f1/f<1;

where f1 is a focal length of the first lens, and f is a focal length of the optical lens.
