Description
The body of the Tsubasa Semi is copied from the Ikonta A, but the viewfinder is contained within a top housing (on the left when the camera is standing vertically). The advance knob is at the left end of the top housing, with a red arrow engraved in red. There is also an accessory shoe, a body release on the right and a folding bed opening button on the left. The back has one red window at the top, protected by a horizontally sliding cover, to control the film advance. The lens is always a 75/3.5 with front-cell focusing, and the aperture is set by an index on top of the shutter housing.
Some markings are common to all the models. The body serial number is engraved on a round plate at the right end of the top housing. Above the viewfinder, there is a KKK logo engraved in red and the words KIGAWA KōGAKU in black. There is also a KIKO TSUBASA logo engraved in the folding struts. The word TSUBASA is also embossed in the front leather, sometimes in a serif font with the T bigger than the other letters, sometimes in a sans serif font with the same height for all the letters.
The first versions
The original Tsubasa Semi can be recognized by the hexagonal trim around the finder window and the Tsubasa marking in front of the top housing.
In 1950[1] and 1951[2], the Tsubasa Semi is first advertised in two variants, both with a Tsubasa 75/3.5 coated lens and a synchronized shutter: the Tsubasa Semi I with B, 25–200 speeds and the Tsubasa Semi II with B, 1–250 speeds.
Later in 1951[3], other variants are advertised, all with a synchronized shutter and a coated f:3.5 lens whose name is not precised: Tsubasa Semi I with T, B, 25–100 speeds, Tsubasa Semi II with B, 10–200 speeds and Tsubasa Semi III with B, 1–200 speeds and self-timer.
The same year 1951[4], the variant names changed again: Tsubasa Semi I with B, 10–200 speeds and Tsubasa Semi III with B, 1–250 speeds and self-timer. This time the lens was a coated Bessel 75/3.5.
The Tsubasa Semi F
The later Tsubasa Semi F has no hexagonal trim around the finder, nor Tsubasa marking in front of the top housing. Instead there are two black lines extending on both sides of the finder window, looking a bit like the Pearl II by Konishiroku.
This version is advertised in 1952[5] in three variants, all having a Bessel 75/3.5 coated lens and a KKK synchronized shutter with ASA bayonet connector: the Tsubasa Semi F1 with B, 10&ndash200 speeds, the Tsubasa Semi F2 with the same speeds and a self-timer and the Tsubasa Semi F3 with B, 1–200 speeds and a self-timer. The shutter rim is engraved K.K.K.
