A camera such as a vide camera having an automatic focusing function, a power focusing function and a power zooming function which allows most reasonable change-over between the functions of the camera. The camera comprises manually operable mode change-over means for alternatively changing over the camera between a zooming mode and a focusing mode, and manually operable instructing means for instructing a direction of movement of a zooming lens system or a focusing lens system for zooming or focusing. When the zooming mode is selected, first actuating means actuates the zooming lens system for zooming in a direction instructed by the instructing means, but when the focusing mode is selected, second actuating means actuates the focusing lens system for focusing operation in a direction instructed by the instructing means. Several forms of instructing means are disclosed.

A camera, comprising: a lens device including a zooming lens system and a focusing lens system; first actuating means for actuating said zooming lens system for zooming; second actuating means for actuating said focusing lens system for focusing; manually operable mode change-over means for alternatively changing over said camera between a zooming mode in which a zooming operation is performed by said first actuating means and a focusing mode in which a focusing operation is performed by said second actuating means; manually operable moving direction instructing means for instructing a direction of movement of said zooming or focusing lens system for zooming or focusing; and control means operable in response to the zooming mode selected by said mode change-over means for causing said first actuating means to perform a zooming operation in response to said moving direction instructing means and operable in response to the focusing mode selected by said mode change-over means for causing said second actuating means to perform a focusing operation in response to said moving direction instructing means. A camera as claimed in claim 1, further comprising focus detecting means for detecting a focused condition of said focusing lens system, and automatic focusing means operable in response to said focus detecting means for driving said second actuating means, whereby, when the zooming mode is selected by said mode change-over means, said automatic focusing means operates in response to said focus detecting means to cause said control means to control said second actuating means to actuate said focusing lens system for focusing.
