ABSTRACT:
Disclosed is a camera loaded selectively with either a first film having perforations formed in side edges or a second film having the same width as that of the first film and no perforations formed in side edges. The camera comprises: a picture size changeover device for selectively setting a photographing picture frame to a first picture size corresponding to the first film and a second picture size corresponding to the second film; a first lens installable and removable in and from the camera and having an image circle corresponding to the first picture size; a second lens installable and removable in and from the camera and having an image circle corresponding to the second picture size; and a device for judging which lens, the first lens or the second lens, to install in the camera. When the judging device judges that the first lens is installed in a state where the picture size is set to the second picture size, the picture size is so set as to be forcibly changed over to the first picture size.
