Semi Dymos
The Semi Dymos (セミダイモス) is a Japanese 4.5×6 folder, sold by Seibi-Dō. It is an Ikonta copy with a folding optical finder and a key at the bottom right to advance the film. There is a Dymos logo embossed in the front leather in handwritten style, the "D" is very large and contains the rest of the letters.
The original model has no body release and has two red windows in the back, protected by a cover that is certainly retracted by turning a knob. It is advertised from 1935 to 1937.
In an advertisement dated January 1936[1] the following variants are offered:
- Model A (A型), Radionar f:6.3 lens, Rulex shutter (¥49);
- Model B (B型), Radionar f:4.5 lens, Light[2] shutter (¥55);
- Model C (C型), Lausar[3] f:4.5 lens, Light shutter (¥59).
The designation of these variants is not very coherent: Kokusan kamera no rekishi also mentions a Model D (D型), identical to the Model C cited above, and says that the Model B sometimes has a Dymos f:4.5 lens and the Model C a Radionar lens.
Later in 1936, the A, B, C, D designations were replaced by the Models E and F. In advertisements dated May[4] and December[5] 1936 the following variants are described:
- Model E (E型), Radionar f:4.5 lens, 5–250 speeds (¥60, case ¥5 extra);
- Model F (F型), Lausar f:4.5 lens, 5–250 speeds (¥63).
