Camera optical lens

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 having a positive refractive power;
• a fourth lens,
• 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 the camera optical lens satisfies following conditions:
• 1.70≤f6/f≤5.00;
• −4.00≤R14/R13≤−1.00;
• −5.00≤f2/f≤−2.00;
• and
• 1.00≤d8/d9≤2.00;
• where
• f denotes a focal length of the camera optical lens;
• f2 denotes a focal length of the second lens;
• f6 denotes a focal length of the sixth lens;
• R13 denotes a curvature radius of the object-side surface of the seventh lens;
• R14 denotes a curvature radius of the image-side surface of the seventh lens;
• d8 denotes an on-axis distance from the image-side surface of the fourth lens to the object-side surface of the fifth lens;
• and
• d9 denotes an on-axis thickness of the fifth lens.
