Camera optical lens

1. A camera optical lens, comprising, from an object side to an image side:

an aperture;

a first lens having a positive refractive power;

a second lens having a negative refractive power;

a third lens having a positive refractive power;

a fourth lens having a negative refractive power;

a fifth lens having a negative refractive power;

a sixth lens having a positive refractive power; and

a seventh lens having a negative refractive power,

wherein the camera optical lens satisfies following conditions:

3.85≤ v 1/ v 2≤4.20; and

−21.00≤ f 2/ f 1≤10.86;

3.40≤ f 3/ f 6≤8.50,

where

f1 denotes a focal length of the first lens;

f2 denotes a focal length of the second lens;

f3 denotes a focal length of the third lens;

f6 denotes a focal length of the sixth lens;

v1 denotes an abbe number of the first lens; and

v2 denotes an abbe number of the second lens.

2. The camera optical lens as described in claim 1 , further satisfying a following condition:

4.50≤ d 1/ d 2≤9.00,

where

d1 denotes an on-axis thickness of the first lens; and

d2 denotes an on-axis distance from an image side surface of the first lens to an object side surface of the second lens.

3. The camera optical lens as described in claim 1 , further satisfying a following condition:

0.40≤( R 9+ R 10)/( R 9− R 10)≤9.50,

where

R9 denotes a curvature radius of an object side surface of the fifth lens; and

R10 denotes a curvature radius of an image side surface of the fifth lens.
