ABSTRACT:
A camera having an image deflection prevention function and which shortens the time from depression of a release button to the commencement of an exposure action while sufficiently maintaining an image deflection correction stroke during the exposure. After a full-depression operation of the release button, a camera CPU determines a drive position and drive direction of a blurring correction optical system based on an output from a correction optical system position sensor. When the drive direction of the blurring correction optical system is toward the center of its drive range, an exposure action is commenced. When the drive direction is away from the center of the drive range, an exposure action is inhibited.
