1. An imaging lens system, comprising:
a first lens having refractive power;
a second lens having a concave object-side surface;
a third lens having refractive power;
a fourth lens 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 the seventh lenses are disposed in sequential order from an object side,
wherein a field of view is 190 degrees or more, and
wherein −4.0<f1/f<−3.0, where f is a focal length of the imaging lens system and f1 is a focal length of the first lens.
