Abstract
A camera system has a camera main body which has a focus detecting device for detecting a focusing state of a photographic optical means in a photographic lens assembly mounted, a display responsive to an output signal from the focus detecting device, and a contact for transmitting the output signal of the focus detecting device to outside of the camera main body. In this camera system, the camera main body are usable with a photographic lens assembly of first type which has an automatic focusing device which is capable of automatically focusing the photographic optical system on the basis of the output signal from the focus detecting device, and with a photographic lens assembly of second type which does not have such an automatic focusing device. When the camera main body is combined with the photographic lens assembly of first type, automatic focusing of the photographic optical system may be performed. When the camera main body is combined with the photographic lens assembly of second type, manual focusing may be performed utilizing a display at the side of the camera main body for displaying the focusing state.
