Camera optical lens

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

• a first lens, a second lens having a positive refractive power, a third lens having a positive refractive power, a fourth lens, a fifth lens, and a sixth lens;
• wherein the camera optical lens further satisfies the following conditions:
• −2.749≤f1/f≤−1.261;
• 1.71≤n2≤2.052;
• 1.709≤n5≤2.062;
• 0.041≤d3/TTL≤0.058;
• where
• f:
• the focal length of the camera optical lens;
• f1:
• the focal length of the first lens;
• n2:
• the refractive index of the second lens;
• n5:
• the refractive index of the fifth lens;
• d3:
• the thickness on-axis of the second lens;
• TTL:
• the total distance from the object side surface of the first lens to the image plane along the optic axis.
