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 following conditions:
1.20≤f2/f1≤7.00;
−3.62≤(R1+R2)/(R1−R2)≤−1.18
1.50≤R6/R5≤5.00
1.20≤d5/d6≤2.00;
where
f1 denotes a focal length of the first lens;
f2 denotes a focal length of the second lens;
R1 denotes a central curvature radius of an object side surface of the first lens;
R2 denotes a central curvature radius of an object side surface of the first lens;
R5 denotes a central curvature radius of an object side surface of the third lens;
R6 denotes a central curvature radius of an image side surface of the third lens;
d5 denotes an on-axis thickness of the third lens; and
d6 denotes an on-axis distance from the image side surface of the third lens to an object side surface of the fourth lens.
