  FIG. 12 is a cross-sectional view of an essential part of the elastic member 490 in a state in which the lens adapter 400 is incorporated in the camera 100. As shown in FIG. 12, the elastic member 490 is formed in a ring shape by a first annular portion 492 disposed on the front side and a second annular portion 493 disposed on the back side. The first annular portion 492 is fitted to the contact portion 424 of the movable mount member 420.
