ABSTRACT:
An auto-focus camera with compensation for object movement along the optic axis of the photo-taking lens determines whether the object speed is greater than a predetermined value. If the result of the determination is negative, normal photography is performed in which a combination of shutter speed and aperture diameter provides a proper exposure in accordance with photometric data. If the result of the determination is affirmative, the aperture is stopped down to a predetermined diameter small enough to provide a large depth of field, and flash photography is performed.
