Claim 4:
5. The camera optical lens as described in claim 1, further satisfying following conditions:

0.26≤f4/f≤0.82;

0.01≤(R7+R8)/(R7−R8)≤0.29; and

0.07≤d7/TTL≤0.26,

where f4 denotes a focal length of the fourth lens, R7 denotes a central curvature radius of the object side surface of the fourth lens, R8 denotes a central curvature radius of an image side surface of the fourth lens, d7 denotes an on-axis thickness of the fourth lens, and TTL denotes a total optical length from an object side surface of the first lens to an image plane of the camera optical lens along an optic axis.
