Abstract
The viewfinder of a camera include one or more lens elements that zoom in coordination with the camera's taking lens, and normal/panoramic masking plates that pivot about horizontal axis in coordination, with moving masking plates for the camera's back frame opening or with signaling elements. Since the panoramic masking plates are not in the image plane, the aperture in a provided aperture plate is a horizontal slit opening, which provides a great depth of focus, to maintain image sharpness, when the masking plates are in the panoramic position.
