Camera optical lens

A camera optical lens, comprising, from an object side to an image side in sequence:

• a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens;
• the first lens has a positive refractive power, the second lens has a negative refractive power, and the third lens has a positive refractive power;
• the fourth lens has a negative refractive power, the fifth lens has a positive refractive power, the sixth lens has a negative refractive power,
• wherein the camera optical lens satisfies the following conditions:
• 0.80≤f1/f≤5.00;
• −4.42≤f4/f≤−0.95;
• and
• −11.00≤R5/d5≤−8.00;
• where,
• f:
• a focal length of the camera optical lens;
• f1:
• a focal length of the first lens;
• f4:
• a focal length of the fourth lens;
• R5:
• a curvature radius of an object side surface of the third lens;
• and
• d5:
• an on-axis thickness of the third lens.
