PROBLEM TO BE SOLVED: To obtain a proper moving picture by a single lens reflex type lens- interchangeable digital camera by using a lens for a silver salt film. SOLUTION: The body of the digital camera is provided with a stop motor for driving the stop of the lens for the silver salt film and a transmitting mechanism having an interlocking claw transmitting its driving force together with a connection terminal for sending a control signal out to a lens for the digital camera having the stop motor inside. Further, a camera control CPU discriminates which of the digital camera lens and silver salt film lens is mounted on the camera body. When it is decided that the silver salt film lens is mounted, the value (F number) of the stop is set to 1.4, 4, or 11 according to an exposure value and exposure control based mainly on an exposure time (shutter speed) is performed. Consequently, the control over the stop becomes stable and an adequate moving picture is obtained. |
