1. A camera optical lens comprising, from an object side to an image side in sequence: a first lens having a negative refractive power, a second lens having a positive refractive power, a third lens, a fourth lens having a negative refractive power, a fifth lens having a positive refractive power, a sixth lens, a seventh lens having a negative refractive power and provided with an image-side surface as a free-form surface; wherein the camera optical lens satisfies conditions of:
|f2/f3|≤0.07;
−0.50≤f2/f4≤−0.30;
0.58≤D12/f≤0.64; and
0.35≤D23/f≤0.45; and
where
f denotes a focal length of the camera optical lens;
f2 denotes a focal length of the second lens;
f3 denotes a focal length of the third lens;
f4 denotes a focal length of the fourth lens;
D12 denotes an on-axis distance from an object-side surface of the first lens to an image-side surface of the second lens; and
D23 denotes an on-axis distance from an object-side surface of the second lens to an image-side surface of the third lens.
