1. A lens imaging system comprising:
a total of five lenses, the five lenses comprising:
a first lens having a convex object-side surface;
a second lens having a convex object-side surface;
a third lens having positive refractive power;
a fourth lens having a convex image-side surface; and
a fifth lens having a refractive power,
wherein the first to fifth lens are sequentially disposed from an object side toward an imaging plane,
wherein a focal length of the second lens is within a range of −10 mm to −7.0 mm,
wherein 1.0<TTL/f<1.2, where TTL is a distance from the object-side surface of the first lens to the imaging plane and f is a focal length of the lens imaging system, and
wherein a radius of curvature of an image-side surface of the third lens is greater than a radius of curvature of an object-side surface of the fourth lens.
