1. An imaging lens system, comprising:
a first lens having refractive power;
a second lens having refractive power;
a third lens having a concave object-side surface;
a fourth lens having refractive power, and having a concave object-side surface;
a fifth lens having refractive power;
a sixth lens having a concave object-side surface; and
a seventh lens having refractive power;
wherein the first to seventh lenses are sequentially disposed from an object side to an imaging side, and
wherein:
20<V1−V3, and
190°≤FOV,
where V1 is an Abbe number of the first lens, V3 is an Abbe number of the third lens, and FOV is a field of view of the imaging lens system.
