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 negative refractive power;
a third lens;
a fourth lens having a positive refractive power;
a fifth lens having a positive refractive power;
a sixth lens having a negative refractive power; and
a seventh lens having a negative refractive power,
wherein the camera optical lens satisfies following conditions:
0.50≤f1/f≤0.80;
1.50≤f6/f7≤5.00;
1.50≤R9/R10≤6.00; and
1.20≤d4/d5≤2.00,
where
f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
f6 denotes a focal length of the sixth lens;
f7 denotes a focal length of the seventh lens;
R9 denotes a curvature radius of an object side surface of the fifth lens;
R10 denotes a curvature radius of an image side surface of the fifth lens;
d4 denotes an on-axis distance from an image side surface of the second lens to an object side surface of the third lens; and
d5 denotes an on-axis thickness of the third lens.
