Camera optical lens

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.
