Claim 0:
1. An imaging lens system comprising:
a first lens comprising a convex object-side surface;
a second lens comprising a convex object-side surface;
a third lens comprising positive refractive power and a convex image-side surface in a paraxial region;
the third lens has a convex object-side surface;
a fourth lens comprising a concave image-side surface;
a fifth lens comprising negative refractive power and a convex object-side surface;
a sixth lens comprising a convex object-side surface and a concave image-side surface in a paraxial region; and
a seventh lens comprising a concave object-side surface,
wherein the first to seventh lenses are sequentially disposed from an object side of the imaging lens system, and
wherein an absolute value of a radius of curvature of an image-side surface of the first lens is greater than an absolute value of a radius of curvature of the object-side surface of the fifth lens.
