摘要： 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.

摘要： An image blur prevention apparatus for use with an image blur prevention device which prevents image blur and a restricting device which restricts movement of the image blur prevention device. The apparatus includes a releasing device which releases the image blur prevention device from a restricted state in which movement of the image blur prevention device is prevented by the restricting device and a holding device which holds a released state in which the image blur prevention device is released from the restricted state. The holding device holds the released state in a holding operation when electric current is supplied thereto. Operation of the holding device switches from the holding operation to a state in which the holding operation is not effected, when the supply of electric current is substantially discontinued.
