Abstract

Present embodiments provide for an optical imaging lens system. The optical imaging lens system may comprise at least four lens elements positioned sequentially from an object side to an image side. By controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least three inequalities, the optical imaging lens system may exhibit better optical characteristics and the total length of the optical imaging lens system may be shortened.
