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;
a fourth lens having a positive refractive power;
a fifth lens;
a sixth lens;
a seventh lens having a positive refractive power;
an eighth lens having a positive refractive power; and
a ninth lens,
wherein the camera optical lens satisfies following conditions:
