Claim 0:
1. A camera optical lens, comprising from an object side to an image side:
a first lens having negative refractive power;
a second lens having positive refractive power;
a third lens having negative refractive power;
a fourth lens having positive refractive power;
a fifth lens having positive refractive power; and
a sixth lens having negative refractive power,
wherein the camera optical lens has a total of six lenses, and further satisfies following conditions:

−2.80≤f1/f≤−1.20;

1.20≤d9/d11≤1.90;

0.09≤(R1+E2)/(R1−R2)≤1.01;
