ADAPTER AND CAMERA SYSTEM |
摘要 |
A camera system includes an interchangeable lens including an image-pickup optical system, a camera body including an image sensor, and an adapter attached between the interchangeable lens and the camera body. The adapter includes a lens side mount to which the interchangeable lens is detachably attached, a camera side mount detachably attached to the camera body, and a tilt-shift unit configured to provide at least one of a tilt operation and a shift operation. A flange focal length of the interchangeable lens is longer than a flange focal length of the camera body. A length 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. |

1. A camera system comprising:
an interchangeable lens including an image-pickup optical system configured to form an optical image of an object; a camera body including an image sensor configured to photoelectrically convert the optical image of the object formed by the image-pickup optical system; and an adapter attached between the interchangeable lens and the camera body, the adapter including a lens side mount to which the interchangeable lens is detachably attached, a camera side mount detachably attached to the camera body, and a tilt-shift unit configured to provide at least one of a tilt operation and a shift operation, wherein a flange focal length of the interchangeable lens is longer than a flange focal length of the camera body, and wherein a length 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. |
