摘要： A camera is capable of displacing a phototaking optical system in the direction of the optical axis by a drive source such as motor and setting the optical system to a plurality of positions. The camera includes a photo-taking optical system, photographing position setting means producing a command signal, a drive source, position detecting means outputting a position signal corresponding to the position of the photo-taking optical system, discriminating means for discriminating the direction of movement of the phototaking optical system, and control means for stopping the drive source and setting the photo-taking optical system at a position corresponding to the command signal as soon as the position indicated by the position signal coincides with the position indicated by the command signal when the discriminating means is discriminating a predetermined first direction of movement, stopping the drive source at a position beyond the position indicated by the command signal and then driving the drive source so that the photo-taking optical system is moved in the first direction when the disciminating means is discriminating a second direction of movement differing from the first direction of movement, and stopping the drive source and setting the photo-taking optical system at the position corresponding to the command signal as soon as the position indicated by the position signal coincides with the position indicated by the command signal.

摘要： A camera has an electrically zoomable lens with two modes. In the first mode, the zooming is continued during the continuation of a manual operation. In the second mode, the zooming is conducted to a focal length corresponding to stored information, which corresponds to a focal length arbitrarily selected in the zooming of the first mode. The stored information is retained even when the second mode is released, and the zooming to the focal length corresponding to the stored information is possble when the second mode is set again.

摘要： 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 judged 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.
