A camera system includes an interchangeable lens (100) including an image-pickup optical system, a camera body (300) including an image sensor, and an adapter (200) attached between the interchangeable lens and the camera body. The adapter includes a lens side mount (201) to which the interchangeable lens is detachably attached, a camera side mount (202) detachably attached to the camera body, and a tilt-shift unit (210, 211) configured to provide at least one of a tilt operation and a shift operation. A flange focal length (X b ) of the interchangeable lens is longer than a flange focal length (X a ) of the camera body. A length (X L ) of the adapter from the lens side mount to the camera side mount in an optical axis direction is equal to or smaller than a difference between the flange focal length of the interchangeable lens and the flange focal length of the camera body. |
