Abstract
The imaging lens system includes a first lens group and a second lens group that are sequentially arranged from an object side to an image side. The first lens group has a negative refractive power and includes a first lens having an image-side surface concave toward the image side. The second lens group includes a lens that is closest to the object side and an aspheric lens that is closest to the image side. The lens that is closest to the object side has a positive refractive power and an object-side surface convex toward the object side. The aspheric lens that is closest to the image side has a positive or negative refractive power and at least one inflection point on an image-side surface thereof.

An imaging lens system comprising:
- a first lens group having a negative refractive power, the first lens group comprising a first lens having an image-side surface concave toward an image side;
- and
- a second lens group comprising a lens that is closest to an object side and an aspheric lens that is closest to the image side, the lens that is closest to the object side has a positive refractive power and an object-side surface convex toward the object side, and the aspheric lens that is closest to the image side has a positive or negative refractive power and at least one inflection point on an image-side surface thereof,
- wherein the first and second lens groups are sequentially arranged from the object side to the image side.
