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 negative 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:
• 0.5≤f1/f≤10;
• 1.7≤n1≤2.2;
• 1.7≤n6≤2.2;
• 0.052≤d1/TTL≤0.2;
• where
• f:
• the focal length of the camera optical lens;
• f1:
• the focal length of the first lens;
• n1:
• the refractive power of the first lens;
• n6:
• the refractive power of the sixth lens;
• d1:
• the thickness on-axis of the first lens;
• TTL:
• the total optical length of the camera optical lens.
