Claim 0:
1. A camera optical lens, comprising, from an object side to an image side:
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 having a positive refractive power; and
a seventh lens having a negative refractive power,
wherein at least one of the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, or the seventh lens comprises a free-form surface, and
wherein the camera optical lends satisfies: 1.50≤d2/d3≤4.00, where d2 denotes an on-axis distance from an image-side surface of the first lens to an object-side surface of the second lens, and d3 denotes an on-axis thickness of the second lens.
