Abstract
The present invention relates to an optical apparatus such as an image-shake correcting device or a camera adapted to have a flash unit built therein or attachable thereto. The optical apparatus comprises an optical-axis deflecting assembly for varying a photographic area by deflecting the optical axis of a photographic optical system, and a control circuit for controlling the operation of the optical-axis deflecting assembly so that the photographic area of the photographic optical system is made to be substantially covered by an illumination area of the flash unit. According to the above-described arrangement, if a subject is located at, for example, a closest-distance position and is not completely positioned within the illumination area of the flash unit, the photographic optical axis is deflected so that the optical axis of the flash unit and the photographic optical axis intersect each other on a closest-distance side, whereby it is possible to position the subject within the illumination area of the flash unit at all times.
