1. An imaging lens system comprising:
a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially disposed in ascending numerical order along an optical axis of the imaging lens system from an object side of the imaging lens system toward an imaging plane of the imaging lens system,
wherein the sixth lens has a convex object-side surface in a paraxial region thereof, and
the imaging lens system satisfies the following conditional expressions:
0.23 mm/°<D1/HFOV<0.35 mm/°
0.15<ImgH/TTL <0.20
where D1 is an effective diameter of the first lens, HFOV is a field of view of the imaging plane in a horizontal direction, ImgH is a height of the imaging plane, and TTL is a distance along the optical axis from an object-side surface of the first lens to the imaging plane.
