1. A camera optical lens, with six lenses, 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 positive power;
a fourth lens having a negative refractive power,
a fifth lens having a positive power; and
a sixth lens having a negative refractive power;
wherein the camera optical lens satisfies the following conditions:
0.35≤f1/f≤0.68;
2.00≤(R3+R4)/(R3−R4)≤5.00;
1.50≤d5/d7≤3.00; and
2.00≤(R7+R8)/(R7−R8)≤15.00;
where
f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
R3 denotes a central curvature radius of an object-side surface of the second lens;
R4 denotes a central curvature radius of an image-side surface of the second lens;
d5 denotes an on-axis thickness of the third lens;
d7 denotes an on-axis thickness of the fourth lens
R7 denotes a central curvature radius of an object-side surface of the fourth lens; and
R8 denotes a central curvature radius of an image-side surface of the fourth lens.
