发明名称 Lens apparatus and camera
摘要 A lens apparatus capable of realizing better optical performance by suppressing an inclination of each lens unit more reliably while shortening the overall length in a collapsed position to the smallest possible level is disclosed. The lens apparatus comprises a fixed member which makes up the body of the apparatus, first and second lens holding members which hold their respective lens units and are movable in the direction of the optical axis with respect to the fixed member and a driving member which engages the first and second lens holding members and drives these first and second lens holding members in the direction of the optical axis.
