Abstract
In a camera comprising a phototaking lens system and a viewfinder lens system having a different optical axis from that of the phototaking lens system, the camera comprises a drive means, for simultaneously zooming the phototaking lens system and the viewfinder lens system, which simultaneously shifts at least one of the lens groups of the phototaking lens system and at least one of the lens groups of the viewfinder lens system. The drive means simultaneously focuses the phototaking lens system and the viewfinder lens system on an object by simultaneously shifting at least one of the lens groups of the phototaking lens system and at least one of the lens groups of the viewfinder lens system based on the position data of the object.
