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 having a positive refractive power;
• and
• a fifth lens having a negative refractive power,
• wherein the camera optical lens satisfies following conditions:
• −2.00≤f2/f≤−1.25;
• −1.50≤f4/f5≤−0.80;
• 1.50≤d6/d8≤3.00;
• −1.50≤(R1+R2)/(R1−R2)≤−1.00;
• and
• 6.00≤R9/R10≤15.00,
• where f denotes a focal length of the camera optical lens, f2 denotes a focal length of the second lens, f4 denotes a focal length of the fourth lens, f5 denotes a focal length of the fifth lens, d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens, d8 denotes an on-axis distance from an image side surface of the fourth lens to an object side surface of the fifth lens, R1 denotes a central curvature radius of an object side surface of the first lens, R2 denotes a central curvature radius of an image side surface of the first lens, R9 denotes a central curvature radius of the object side surface of the fifth lens, and R10 denotes a central curvature radius of an image side surface of the fifth lens.
