Abstract
An imaging lens system includes a lens group including a plurality of lenses, and an optical path folding member disposed on an image side of the lens group, wherein −1.2<fR/PL<−0.40, where fR is a focal length of a rearmost lens disposed closest to an imaging plane in the lens group, and PL is a distance from an incident surface of the optical path folding member to an exit surface of the optical path folding member.

An imaging lens system comprising:
- a lens group comprising a plurality of lenses sequentially disposed along an optical axis of the imaging lens system from an object-side surface of the lens group toward an imaging plane of the imaging lens system;
- and
- an optical path folding member disposed on the optical axis between an image-side surface of the lens group and the imaging plane,
- wherein the plurality of lenses comprise a fourth lens having a convex object-side surface, and
- 1.52<(TTL+ImgHT)/PL<2.32, where TTL is a distance along the optical axis from the object-side surface of the lens group to the imaging plane, ImgHT is a height of the imaging plane, and PL is a distance along the optical axis from an incident surface of the optical path folding member to an exit surface of the optical path folding member.
