发明名称 Camera having special photography function
摘要 A camera having a special photography function comprises a focus detecting circuit for detecting a state of focus of a subject, a focus-position altering circuit for altering a focus position of a photographic optical system in response to a detection result provided by the focus detecting circuit, and a special-photography executing circuit for executing special photography utilizing multiple exposure. The special-photography executing circuit is arranged to control the focus-position altering circuit in response to a release operation to shoot one exposure on a photosensitive portion with the photographic optical system placed in an in-focus position and continuously shoot at least one exposure on the same photosensitive portion with the photographic optical system placed in a defocused position on a closest-distance side, thereby effecting the multiple exposure.
