Patent number: 11630289Abstract: An image capturing lens system includes three lens groups including five lens elements. The three lens groups are, in order from an object side to an image side: first, second and third lens groups. The five lens elements are, in order from the object side to the image side: first, second, third, fourth and fifth lens elements. The first lens element has an object-side surface being convex in a paraxial region thereof. The second lens element has negative refractive power. At least one lens element has an inflection point. A focal length of the image capturing lens system is varied by changing axial distances between the three lens groups in a zooming process. The image capturing lens system has a long-focal-length end and a short-focal-length end. The second lens group is moved relative to the first lens group along an optical axis in the zooming process.Type: GrantFiled: October 8, 2020Date of Patent: April 18, 2023Assignee: LARGAN PRECISION CO., LTD.Inventors: Hsiang-Chi Tang, Tzu-Chieh Kuo
