Further, the following conditional expression (1) is satisfied: 1.0<f1/f<2.5??(1) where f1: is the focal length of the first lens group, and f: the focal length of the entire system.Type: GrantFiled: May 15, 2020Date of Patent: September 26, 2023Assignee: Nikon CorporationInventors: Keiko Yamada, Ryosuke Imajima, Wataru Tatsuno, Haruo Sato
