Abstract: A zoom view finder includes a stationary lens group, a variable power lens group movable relative to the stationary lens group and a drive mechanism which can be connected to a drive source to drive the variable power lens group. A unified finder case which supports the stationary lens group, the movable variable power lens group and the drive mechanism is provided.

Abstract: A supporting apparatus for an optical element includes a supporting frame which is adapted to support the optical element. The optical element is provided with at least one elastic engaging portion integral therewith. The supporting frame is provided with an engaging portion in which the elastic engaging portion of the optical element can be elastically engaged.

Abstract: A zoom camera is provided that includes a zoom photographing optical system which has a predetermined zoom range and which is retractable to a position rearwardly of the zoom range. A zoom finder is also provided which varies the field of view of the finder in accordance with the focal length of the zoom photographing optical system. The zoom finder is driven by a zoom motor which also drives the zoom photographing optical system. A lens driving mechanism which is driven by the zoom motor, a lens moving mechanism which moves the movable variable power lens group to a predetermined position in association with the movement of the lens driver within the zoom range of the zoom photographing optical system, and an idling device which idles the lens driving mechanism so as not to transmit the movement thereof to the lens moving mechanism when the zoom photographing optical system is moved beyond the zoom range are also provided.
