It is a simple TLR with a boxy shape and geared lenses for focusing. It is equipped with a loupe and a synchronized shutter. There is an advance knob on the right hand side, and a red window in the back near the bottom, protected by a vertically sliding cover. It is said that the Tsubasaflex is a copy of the Ricohflex IIIB.
It is advertised in March 1951 with a Tsubasa 80/3.5 coated lens and T, B, 25, 50, 100, 150 shutter speeds. The name plate is black with a thick chrome frame and Tsubasaflex written in lowercase chrome letters.
In advertisements dated May and June, the name plate is now written Tubasaflex in lowercase and JUNIOR in small uppercase letters, and the surrounding chrome frame is finer. The lens is still a 80/3.5 but no name is given. Three variants of the Tubasaflex Junior are offered:
- Model I with T, B, 25–150 speeds;
- Model II with B, 10–200 speeds;
- Model III with B, 1–200 speeds and self-timer.
In an advertisement dated November, some changes are visible. A button has appeared on the right hand side plate, it is probably the body release that is mentioned by the advertisement. The strap lugs are different. There is a decorative metal plate covering nearly all the front of the body, shaped to look like a movable (focusing) front plate. The name plate is now all metal with TUBASAFLEX written in uppercase black letters, and the JUNIOR marking has disappeared. Two versions of the Tubasaflex are offered, both with a Bessel 75/3.5 coated lens:
- Model I with B, 10–200 speeds;
- Model II with B, 1–200 speeds and self-timer.
A model I has been observed in an online auction but the lenses were Tsubasa Anastigmat 80mm f:3.5.
Some version of the Tubasaflex has also been reported with a lens named Lause.
This camera is succeeded in 1952 by the Graceflex.
