Claim 10:
11. An imaging lens system comprising:
a plurality of lenses disposed on an object-side of an imaging plane, the plurality of lenses including a first lens, a second lens having negative refractive power, a third lens, a fourth lens, a fifth lens, a sixth lens comprising a concave image-side surface in a paraxial region, and a seventh lens disposed in order from an object side,
wherein

−2.0<(ImgH/(f*tan(FOV/2))−1)*100<2.0, and

TTL/ImgH<1.5,

where ImgH is a height of the imaging plane, f is a focal length of the imaging lens system, FOV is a field of view of the imaging lens system, and TTL is a distance from an object-side surface of a lens, from among the plurality of lenses, disposed closest to the object side, to the imaging plane, and
wherein a radius of curvature of an object-side surface of the second lens is greater than a radius of curvature of an object-side surface of the seventh lens.
