A camera capable of operating in a red-eye prevention mode. The camera has an electronic flash device which is activated by a drive circuit in synchronization with the exposure. The electronic flash device also serve as a pre-light-emission device capable of performing pre-light-emission for the purpose of preventing red-eye effect. When it is judge from the photographing condition that red-eye effect may occur, a controller activates the electronic flash device to effect a pre-light-emission for reducing the size of pupils of eyes of a person to be photographed, before the main flashing which is executed in synchronization with the exposure.

The present invention is designed such that during flash photographing which involves pre-light emission for preventing red eye, focus adjustment is effected on the basis of focus adjustment information detected during the time from after the pre-light emission is effected until shutter release is effected and therefore, the time lag from the detection of the focus adjustment information until the shutter release can be minimized and a photo-taking lens can be reliably focused to a desired object even during flash photographing which involves the pre-light emission.
