Abstract
A lens apparatus comprises a fixed barrel, a movable barrel, a mechanism configured to move the movable barrel along an optical axis by rotation of the movable barrel around the optical axis, and an operating member disposed through the fixed barrel and rotationally operated. The operating member comprises a rotating shaft and an engaging portion eccentric from the rotating shaft. The rotating shaft is rotated with the operating member being rotationally operated, the engaging portion is engaged with a guide formed in the movable barrel along the optical axis. At least a part of the engaging portion is located outside the rotating shaft in a direction orthogonal to the rotating shaft. Rotation of the operating member causes the engaging portion to slide on the guide, the movable barrel to rotate around the optical axis, and the mechanism to move the movable barrel along the optical axis.
