Lens apparatus and imaging system including the same

Abstract

A lens apparatus includes an imaging optical system includes an imaging optical system including a plurality of lenses, a first holding member holding at least a first lens closest to an object among the plurality of lenses, and configured to move in an optical axis direction of the imaging optical system to perform focusing, a barrel member provided on an outside of the first holding member, and a control unit configured to control a driving unit configured to move the first holding member. When focus is at infinity, an edge surface on an object side of the barrel member is positioned on the object side of a surface vertex of an object-side surface of the first lens. When focus is at infinity, an edge surface on the object side of the control unit is positioned on the object side of the surface vertex.
