Claim 0:
1. 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;
a fourth lens;
a fifth lens having a positive refractive power; and
a sixth lens having a negative refractive power;
wherein an object-side surface of the second lens is convex in the paraxial region;
wherein the camera optical lens satisfies the following conditions:
0.25≤d10/TTL≤0.50;
0.55≤f1/f≤1.00; and
−2.10≤f2/f≤−1.00;
where f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
f2 denotes a focal length of the second lens;
d10 denotes an on-axis thickness from an image-side surface of the fifth lens to an object-side surface of the sixth lens; and
TTL denotes a total optical length from an object-side surface of the first lens to an image surface of the camera optical lens along an optical axis.
