Abstract
A lens mount capable of suppressing play of an interchangeable lens against a camera body. The lens mount of the interchangeable lens includes a fixed mount part having a female screw portion, a movable mount part having a male screw portion, and an arm part protruding from the movable mount part. When the movable mount part is rotated about an optical axis by turning the arm part about the optical axis from a state where a mount surface of the camera body and a lens-side mount surface of the fixed mount part are in contact and a bayonet-lug portion of the camera body and a lug portion of the movable mount part do not overlap on an optical axis projection, the movable mount part moves toward the fixing portion in the optical axis direction, as the male screw portion is screwed with the female screw portion.
