The lens system includes a second free-curved lens being asymmetrical with respect to the optical axis. A sag amount of the second free-curved lens in a circle separated from the optical axis by a length having a predetermined ratio with respect to a minimum image height has extrema outside of a first intersection points between a first surface passing through the optical axis and parallel to longer sides of the imaging element and the circle, and a second intersection point between a second surface passing through the optical axis and parallel to shorter sides of the imaging element and the circle. Each of the extrema is greater than the sag amount at the first intersection point or the second intersection point by 0.01 mm or greater."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lens system, camera system, and imaging system","description":"A lens system forms an image on an imaging element having a quadrilateral shape disposed on an optical axis.
