The Olympus AF-10 Twin of 1991 has a biaxial (twin-lens) system so the user can switch between a 35mm wide-angle lens and a 70mm telephoto lens. A button on top of the camera lets you switch between lenses (it adjusts the viewfinder as well). It has autofocus and auto-exposure, with shutter speeds of 1/15 to 1/750s. Auto-flash (can be switched off or switched to fill-in manually)
