Claim 0:
1. An optical camera lens, comprising, from an object side to an image side:
a first lens;
a second lens having a positive refractive power;
a third lens;
a fourth lens;
a fifth lens;
a sixth lens;
a seventh lens;
an eighth lens; and
a ninth lens,
wherein the optical camera lens satisfies following conditions:

1.806≤f1/f≤3.20;

2.50≤R12/R11≤4.50; and

2.00≤d3/d4≤8.00,

where f denotes a focal length of the optical camera lens, f1 denotes a focal length of the first lens, R11 denotes a central curvature radius of an object side surface of the sixth lens, R12 denotes a central curvature radius of an image side surface of the sixth lens: d3 denotes an on-axis thickness of the second lens, and d4 denotes an on-axis distance from an image side surface of the second lens to an object side surface of the third lens.
