The optical image-forming lens system, the photographic unit, and the electronic components.

Abstract

The invention relates to an optical imaging lens system comprising seven lens elements in order from object to image along the optical path: the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element, the sixth lens element, and the seventh lens element. Each of the seven lens elements has an object-facing surface facing the object and an image-facing surface facing the image. The object-facing surface of the third lens element is concave in its anti-axial region. The image-facing surface of the sixth lens element is convex in its anti-axial region. The image-facing surface of the seventh lens element has at least one inflection point. The optical imaging lens system also includes a lens aperture diaphragm positioned between the fourth and fifth lens elements. The invention also relates to an imaging device and electronic equipment.
