Abstract
An imaging lens system includes: a first lens having positive refractive power; a second lens having refractive power; a third lens having negative refractive power; a fourth lens having positive refractive power and a convex image-side surface; a fifth lens having refractive power; a sixth lens having refractive power; a seventh lens having a concave image-side surface; and an eighth lens having negative refractive power, wherein the first to eighth lenses are arranged sequentially from the object side toward the imaging surface, wherein at least one of the first to eighth lenses has an aspherical surface, wherein the imaging lens system has a total of eight lenses with refractive power, and wherein TTL / 2IMGHT<0.78, where TTL is the distance from the object side of the first lens to the imaging surface, and 2IMGHT is the diagonal length of the imaging surface.
