ABSTRACT:
A camera arranged to permit photographing by taking full advantage of a spurious telephoto shooting function irrespective of the current state of facilities of photofinishing laboratories is provided with an image plane frame change-over mechanism which acts in response to mode selection made by a mode change-over switch to effect change-over of the size of an image plane frame between a normal image plane frame having a normal image plane frame size and a spurious telephoto image plane frame having a size not exceeding 1/2 of the normal image plane frame size and a restricting member which causes a shooting image plane set by the spurious telephoto image plane frame to become containable within a range of film usable in taking a panorama shot. Therefore, in the spurious telephoto mode, a spurious telephoto shot is taken within the range of film for a panorama shot.
