Claim 0:
1. A lens apparatus comprising:
a holding barrel configured to hold a lens;
an operation member;
an exterior barrel configured to hold the operation member rotatably around an optical axis; and
a fixed barrel,
wherein the holding barrel is integrally fixed to the exterior barrel, and when the holding barrel and the exterior barrel move in an optical axis direction relative to the fixed barrel, an imaging state and a retracted state in which an overall length is shorter than that of the imaging state are switchable,
wherein when the operation member is rotated in one direction around the optical axis in the imaging state, the operation member gets engaged with the fixed barrel and the imaging state gets locked,
wherein when the operation member is rotated in the one direction around the optical axis in the retracted state, the operation member gets engaged with the fixed barrel and the retracted state gets locked, and
wherein when the operation member is rotated in the other direction around the optical axis, the operation member gets disengaged from the fixed barrel, and the imaging state or the retracted state gets unlocked and switchable.
