The Riken Super Ricohflex is a very simple, lightweight twin-lens reflex. The camera was introduced in 1955 and production continued into the early 60s. The Super Ricohflex was made in Japan by the Riken Institute and now known as Ricoh after 1963. The early simple camera uses 120 roll films only but later Super Ricohflex cameras could be converted to use 127 roll films or 35mm film with the right inserts and wind knob attachment. The early Riken shutter has speeds of 1/10 to 1/200 of a second plus B but later models came with 1/10 to 1/300 of a second plus B and possibly 1 second to 1/500 of a second plus B. The 120 film only model had one red window with a sliding metal closer in the back cover but the multi film models had two. The original basic cameras sold for around $20.00 with insert costing $10.00 each and $5.00 for each accessory auto-stop film advance knob. The cameras came with a 3.5/8cm Ricoh Anastigmat taking lens and the same size Ricoh viewer lens. The camera has a manually set shutter, cable shutter release socket, shutter speed indicator, flash attachment socket, cold shoe, 3.5 to 16 aperture settings, 3.5 feet to infinity focus range, ground glass waist high viewfinder with self-erecting hood, wide field magnifier for critical focus, and two hard points to attach a carry strap. The camera also has an eyelevel viewfinder method using two eyes. You open the viewfinder and by looking through the magnifier with one eye you frame the picture with that eye and see the picture with the other outside the viewfinder.
