The Orionflex is a Japanese 6×6 TLR camera of the early 1950s, about which little is known. The camera was not announced or advertised in Japan, and was perhaps made for export only.
The Orionflex, dated c.1952, is sometimes attributed to a "Kikawa Optical Works", certainly a wrong name for Kigawa Kōgaku. The attribution to Kigawa is perhaps based on the similarity between the main body of the Orionflex and that of the Tsubasaflex.
The Orionflex is an ordinary TLR, with externally geared lenses. The film advance is by a knob on the photographer's right, and is certainly controlled by a red window. The L-shaped back is locked by a latch at the bottom. The plain viewing hood has no sports finder. The name ORIONFLEX is inscribed on a nameplate placed above the front plate.
The camera has Orion Anastigmat 8.0cm f/3.5 lenses. The shutter is unnamed and reportedly gives B, 25–100 speeds; it is synchronized via a pin at the bottom, and tripped by a lever on the side.
