Claim 8:
9. The optical camera lens as described in claim 1, further satisfying following conditions:

0.51≤f8/f≤1.56;

−2.23≤(R15+R16)/(R15−R16)≤−0.69; and

0.04≤d15/TTL≤0.12,

where f8 denotes a focal length of the eighth lens, R15 denotes a central curvature radius of an object side surface of the eighth lens, R16 denotes a central curvature radius of an image side surface of the eighth lens, d15 denotes an on-axis thickness of the eighth 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.
