A camera viewfinder having a plurality of lens groups, wherein a photographing optical system of the camera is separate from the viewfinder. The viewfinder includes a parallax error compensating and diopter adjusting lens group which is one of the plurality of lens groups. The viewfinder further includes a guide member for guiding the compensating and adjusting lens group in a direction that intersects the optical axis of the viewfinder so as to move the lens group towards and away from the optical axis of the photographing optical system. In addition, there is provided an object distance detecting mechanism for detecting a distance of an object to be photographed, and a movement control mechanism for continuously moving the parallax error compensating and diopter adjusting lens group along the guide member in accordance with the object distance detected by the object distance detecting mechanism.
