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 positive refractive power;
a third lens having a negative refractive power;
a fourth lens having a positive refractive power; and
a fifth lens having a negative refractive power,
wherein the camera optical lens satisfies the following conditions:

1.10≤f1/f≤1.50;

0.40≤R3/R4≤1.00;

1.00≤d5/d6≤2.00;

−1.50≤R7/R8≤−1.00; and

FOV≥89°,

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, d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens, R7 denotes a central curvature radius of the object side surface of the fourth lens, R8 denotes a central curvature radius of an image side surface of the fourth lens, and FOV denotes a field of view of the camera optical lens.
