Claim 9:
10. 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 from an object to an image side,
wherein the imaging lens system comprises no more than six lenses having refractive power,
wherein the third lens, the fourth lens, and the sixth lens each have a same refractive power as a refractive power of the first lens, and the second lens and the fifth lens each have a different refractive power from the refractive power of the first lens,
wherein the third lens has a convex image-side surface,
wherein an absolute value of a radius of curvature of an object-side surface of the fifth lens is less than an absolute value of a radius of curvature of an image-side surface of the third lens,
wherein an F number of the imaging lens system is less than 2.0,
wherein OAL/(Img HT)<1.50,
where OAL represents a distance from an object-side surface of the first lens to an imaging plane, and Img HT represents a half of a diagonal length of the imaging plane,
wherein a thickness of the first lens is greater than a thickness of the sixth lens, and
wherein a distance from an image-side surface of the first lens to an object-side surface of the second lens is greater than a distance from an image-side surface of the fifth lens to an object-side surface of the sixth lens.
