Another half-frame Demi camera. The behind-the-lens Lens Shutter enabled interchangeable lenses to be attached on a screw-on mount.

Two interchangeable lenses were available: the normal SD 28mm lens and telephoto SD 50mm f/2.8 lens. The viewfinder had frames to match the lenses. Otherwise, the camera was the same as the original Demi.
