Claim 0:
1. A camera optical lens, comprising nine lenses, the nine lenses from an object side to an image side being:
a first lens with a negative refractive power;
a second lens with a positive refractive power;
a third lens with a positive refractive power;
a fourth lens with a positive refractive power;
a fifth lens with a positive refractive power;
a sixth lens with a negative refractive power;
a seventh lens with a negative refractive power;
an eighth lens with a positive refractive power; and
an ninth lens with a negative refractive power;
wherein the camera optical lens satisfies following conditions:

−2.00≤f1/f≤−0.80; 2.00≤d11/d12≤12.00;

where
f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
d11 denotes an on-axis thickness of the sixth lens;
d12 denotes an on-axis distance from an image-side surface of the sixth lens to an object-side surface of the seventh lens.
