ABSTRACT:
A camera having: a viewfinder optical system including a stationary objective lens, first and second prisms, a stationary eyepiece lens, and first and second variable-power lenses, that advance or withdraw in the optical-axis direction responsive to zooming movement of a photographing lens array, a viewfinder structure member for retaining the viewfinder optical system, an eyepiece variable-power lens inserted into the optical path of the viewfinder optical system, a viewfinder panoramic field mask united with an eyepiece variable-power lens frame for retaining the eyepiece variable-power lens, a lens constraining spring that, when the viewfinder panoramic field mask is inserted into the optical path of the viewfinder optical system, constrains the eyepiece variable-power lens to abut against the viewfinder structure member for accurate positioning, upper and lower interceptive masks for changing picture size, a first rack extending in a direction in which the interceptive masks move, a second rack extending in a direction in which the viewfinder panoramic field mask moves, a panoramic-mode setting gear engaging the first and second racks, and a viewfinder objective lens sliding axis pin having one end retained by the stationary objective lens or first prism to guide movement of the first and second variable-power lenses along the optical axis.
