The Firstflex are Japanese 6×6cm TLR cameras for 120 film, made by Tokiwa Seiki in about 1951-55, with the viewing and taking lenses linked by external gear-teeth. McKeown lists several models, describing them as cheaply made:
- Firstflex I (1951): First Anastigmat 80 mm f/3.5. Unidentified shutter, 1/10 - 1/200 second plus B, synchronised with an ASA bayonet. Nameplate in upright capitals, chrome-on-black. A very similar camera is named the Kenflex (pictured below).
- Firstflex II (1951): First anastigmat as above, shutter speeds 1/5 - 1/200 second, plus B, synchronised with an ASA bayonet, now on the camera body. Nameplate in italic capitals (as illustrated below), the same text style as that of the Kenflex.
- Firstflex II (1952): Lens now engraved as a Special First Anastigmat (but still 80 mm f/3.5), in an MSK-II shutter, with speeds 1 - 1/400 second, plus B, still synchronised with an ASA bayonet, now once again mounted on the shutter. Embossed chrome nameplate. Focusing hood incorporates an eye-level Albada finder.
- Popular Firstflex PII (1953): Special First Anastigmat, in unidentified shutter with speeds 1/10 - 1/200 second, plus B.
- Firstflex LIII (1955): First Anastigmat in MSK-II shutter; very much like the 1952 camera, but without the Albada finder.
All the cameras use a winding knob for advancing the film, with a red window in the back, with a sliding cover.
