A camera system includes a camera body and an interchangeable lens. The camera body includes a camera-side mount, a groove which is disposed in rear of a mount abutting face of the camera-side mount in the direction of the optical axis and which is formed on an outer circumference of the camera-side mount, and a ring-shaped elastic member which is disposed in the groove. The interchangeable lens includes a lens-side mount which is mountable on the camera-side mount, and a tubular protruding part which is disposed in rear of a mount abutting face of the lens-side mount in the direction of the optical axis and which has an inner circumferential face arranged to come into pressure contact with the ring-shaped elastic member.
