1. A camera optical lens comprising, from an object side to an image side:
a first lens with a positive refractive power;
a second lens with a negative refractive power;
a third lens with a negative refractive power;
a fourth lens with a positive refractive power; and
a fifth lens with a negative refractive power;
wherein the camera optical lens satisfies the following conditions:
0.40≤f1/f≤0.70;
−3.50≤f5/f≤−1.20;
2.00≤(R5+R6)/(R5−R6)≤20.00;
1.20≤d4/d5≤5.00; and
−15.00≤R7/R8≤−1.50;
where
f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
f5 denotes a focal length of the fifth lens;
R5 denotes a curvature radius of an object-side surface of the third lens;
R6 denotes a curvature radius of an image-side surface of the third lens;
R7 denotes a curvature radius of an object-side surface of the fourth lens;
R8 denotes a curvature radius of an image-side surface of the fourth lens;
d4 denotes an on-axis distance from an image-side surface of the second lens to the object-side surface of the third lens; and
d5 denotes an on-axis thickness of the third lens.
