Camera Lens

摘要

The present invention discloses a camera lens composed of five ultrathin and high-luminous flux wide angle lenses with excellent optical properties. The lenses are lined up in turn from the object side as follows: a first lens with positive refractive power, a second lens with negative refractive power, a third lens with negative refractive power, a fourth lens with positive refractive power a fifth lens with negative refractive power. The camera lens meets specific conditions.

1. A camera lens, comprising, lined up in turn from the object side:
a first lens with positive refractive power; a second lens with negative refractive power; a third lens with negative refractive power; a fourth lens with positive refractive power; a fifth lens with negative refractive power; wherein the camera lens satisfying the following specific conditions:
0.80≦f1/f1.00−5.00≦f3/f−3.00−0.80≦(R1+R2)/(R1−R2)≦−0.300.05≦(R3+R4)/(R3−R4)≦0.400.25≦d7/f≦0.35 where, f is the overall focal distance of the camera lens; f1 is the focal distance of the first lens; f3 is the focal distance of the third lens; R1 is the object side curvature radius of the first lens; R2 is the image side curvature radius of the first lens; R3 is the object side curvature radius of the second lens; R4 is the image side curvature radius of the second lens; d7 is the center thickness of the fourth lens.
