ABSTRACT:
According to a photographing apparatus of this invention, tilt angles of a photographing optical system at least at two points on a plane and a lens position in an in-focus state or in a zooming state are prestored before a photographing operation. When an object moving on the plane is photographed in practice, the focusing or zooming operation of the photographing lens system is appropriately performed in accordance with the tilt angle of the optical photographing system directed toward the object and the prestored data.
