Classification: CPC G | IPC G

Claim 0:
1. A camera optical lens, comprising, from an object side to an image side:
a first lens having a positive refractive power;
a second lens having a negative refractive power;
a third lens having a negative refractive power;
a fourth lens having a positive refractive power;
a fifth lens;
a sixth lens having a positive refractive power; and
a seventh lens having a negative refractive power,
wherein an object side surface of the seventh lens is concave at a paraxial position,
wherein the camera optical lens satisfies following conditions:

59.00≤v1≤82.00;

3.00≤R12/R11≤10.00, and

0.04≤(R13+R14)/(R13−R14)≤0.38,

where
v1 denotes an abbe number of the first lens;
R11 denotes a central curvature radius of an object side surface of the sixth lens;
R12 denotes a central curvature radius of an image side surface of the sixth lens;
R13 denotes a central curvature radius of an object side surface of the seventh lens; and
R14 denotes a central curvature radius of an image side surface of the seventh lens.
