A camera uses a program shutter as a shutter device. When an exposure value becomes larger than EV9, a stop of the camera is closed down so as to increase an f-number. In a case that the camera is loaded with a photographic film having film sensitivity of ISO 1000 or more, an upper limit of a focus set position of a taking lens is fixed to 3 m. By utilizing a depth of field, a picture is taken in a state that a blur is reduced, relative to a subject existing within a range from a comparatively short photographic-distance to a far photographic-distance. |
