In a camera system that includes a lens unit and a camera body, the camera body includes: an image blur detecting unit that detects image blur in a plurality of directions; an image blur correcting unit that performs image blur correction in the plurality of directions; a determining unit that determines whether a mounted lens unit is a lens unit that performs the image blur correction; and an image blur correction control unit that performs control in such a way that, when a determination result of the determining unit is true (Yes), the image blur correcting unit performs the image blur correction only in specific directions from among the plurality of directions, and that performs control in such a way that, when the determination result of the determining unit is false (No), the image blur correcting unit performs the image blur correction in the plurality of directions. |

1. A camera system that includes a lens unit and a camera body that the lens unit is attached to or detached from, wherein
the camera body includes:
an image blur detecting unit that detects image blur in a plurality of directions, the image blur being associated with movement of the camera system in the plurality of directions;an image blur correcting unit that performs image blur correction in the plurality of directions;a determining unit that determines whether the lens unit mounted onto the camera body is a lens unit that performs the image blur correction; andan image blur correction control unit that performs control in such a way that, when the determining unit determines that the lens unit mounted onto the camera body is the lens unit that performs the image blur correction, the image blur correcting unit performs the image blur correction only in specific directions from among the plurality of directions, the specific directions including at least a roll direction that is a direction of rotation with respect to an optical-axis direction of the lens unit, and that performs control in such a way that, when the determining unit determines that the lens unit mounted onto the camera body is not the lens unit that performs the image blur correction, the image blur correcting unit performs the image blur correction in the plurality of directions including the specific directions, and the image blur correction control unit performs control in such a way that an image blur correction cycle in the specific directions when the image blur correcting unit performs the image blur correction only in the specific directions is shorter than the image blur correction cycle in the specific directions when the image blur correcting unit performs the image blur correction in the plurality of directions. |
