A lens-interchangeable camera includes a focus detector performing focus detection and a controller performing a drive control of a lens based on a defocus amount. The controller finishes focusing operation without driving the lens when the defocus amount is out a range of a first in-focus determination width, and performs the focusing operation when the defocus amount is out a range of the first in-focus determination width. The controller finishes the focusing operation without performing the focus detection again after completing the drive when the defocus amount is out a range of a second in-focus determination width, and performs the focus detection again after completing the drive when the defocus amount is out a range of the second in-focus determination width. The second in-focus determination width is set to be greater than the first in-focus determination width and be greater than or equal to a drive limit value.

An interchangeable lens which is removably mounted on a camera body including an image sensor includes a tilt unit configured to move a lens unit in a tilt direction with respect to the image sensor, a shift unit configured to move the lens unit in a shift direction with respect to the image sensor, a changing unit configured to change a relative angle between the shift unit and the tilt unit by relatively rotating the shift unit and the tilt unit, a detection unit configured to detect the relative angle, and a control unit configured to transmit to the camera body a detection result of the relative angle detected by the detection unit.
