Abstract:
The lens apparatus includes a first operating member rotatable around an optical axis of an optical element so as to move the optical element in an optical-axis direction, a first elastic member configured to press the first operating member, a second elastic member configured to press the first operating member, a second operating member rotatable around the optical axis and movable in the optical-axis direction, and a first interposition provided between the first operating member and the second operating member. When the second operating member is moved in the optical-axis direction, the first interposition is moved in the optical-axis direction without rotating around the optical axis and presses the first elastic member and the second elastic member.
