1. An optical apparatus comprising:
a holding frame holding an optical system;
an intermediate member;
a driving unit moving the intermediate member in a direction along an optical axis of the optical system;
a biasing member biasing the holding frame in a direction along the optical axis with respect to the intermediate member; and
a detection unit detecting the intermediate member, wherein the optical apparatus takes:
a first state in which a part of the holding frame is brought into contact with a part of the intermediate member according to a biasing force of the biasing member; and
a second state in which the holding frame is separated from the intermediate member against the biasing force of the biasing member, and
wherein the driving unit is able to move the intermediate member in a direction along the optical axis in either the first state or the second state, and the detection unit is able to detect the intermediate member at least in the second state.
