11 Claims

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:
