ABSTRACT:
In a zoom finder of a zoom lens camera, a movable variable power lens is supported to move in an optical axis direction and is moved to predetermined positions by a cam member which is driven in association with movement of the zoom lens. The cam member is provided with a groove or a projection at a reference position. The cam member is held in the reference position by a holding member which is engaged by the groove or the projection before assembling the finder to the zoom lens camera.
