The Easternflex is a Japanese 6×6 TLR of the mid-1950s, perhaps made by Tōyō Seiki Kōgaku (see below).

General description

The Easternflex is a regular copy of the Rolleicord. The whole front standard is moved back and forth for focusing. The film advance and focus knobs are on the photographer's right. There is a sportsfinder in the viewing hood. The name EASTERNFLEX is inscribed on a nameplate above the front plate, and no company name is visible.

The release button is placed at the bottom of the front standard, on the photographer's right. There is an accessory shoe on the left plate. The synch post is probably buried at the bottom of the left plate.


The camera was featured in the news column of the Sankei Camera issue dated June 1955.[1] It was called Easternflex A (イースタンフレックスA) and attributed to "Tōyō Seiki" (東洋精機).[2] It was announced with semi-automatic film advance, a TSK shutter (B, 1–200, self-timer), a PC synch post and Unicor[3] 75/3.5 four-element lenses made by Union Kōgaku.[4]

The actual examples observed so far fall in two different versions. They all have a Ceres shutter (B, 1–300, self-timer).

The first version has similarities with the Elbowflex and Prince Junior. It has J-Luminar lenses and a round exposure counter window at the top right.[5] There is no soft release thread and no depth-of-field scale.

The second version has Lumicor 8cm f/3.5 lenses. The strap lugs are very different and no exposure counter is visible. The advance and focus knobs are bigger, the distance scale is black and there is a depth-of-field scale. The accessory shoe is placed further to the bottom. Of this second versions, some examples have a soft release thread and others don't, and there are variations in the back latch.[6]


The following arguments lead to the probable conclusion that the Easternflex, or at least its first version, was made by Tōyō Seiki Kōgaku:

  • the attribution of the Easternflex A to "Tōyō Seiki";
  • the use of a TSK shutter on the Easternflex A;
  • the similarities of the body (specially the first version) with the Elbowflex and Prince Junior;
  • the use of J-Luminar lenses and a Ceres shutter on the first version, as on the Prince Junior.
