Claims

[Scope of claim for utility model registration] (1) A set aperture control mode in which the aperture of the photographic lens is controlled by a preset aperture, and an automatic mode in which the aperture is automatically controlled to the appropriate exposure according to the subject light that passes through the photographic lens. In a camera that has an aperture control mode, it is possible to identify whether the electronic flash device is in TTL flash control mode or other flash control mode, and to
a signal generating means that generates a first signal when in the dimming mode and a second signal when in other dimming modes; and a warning when the second signal is generated when in the automatic aperture control mode. A camera characterized in that it has a warning means. (2) In a camera that has a set aperture control mode in which the aperture of the photographic lens is controlled at a set aperture, and an automatic aperture control mode in which the aperture is automatically controlled to an appropriate exposure according to the subject light transmitted through the photographic lens. , Identifies whether the electronic flash device is in TTL dimming mode or other dimming mode, and
a signal generating means for generating a first signal in a light control mode and a second signal in a light control mode other than the light control mode; A camera characterized in that it has prohibition means for prohibiting.
