The Walcon Semi is based on the contemporary Zenobia C made by Daiichi Kōgaku, with a different lens and shutter. The top housing is slightly modified, with slightly smoother contours. The advance knob is different too. There is a film reminder dial on the right end of the top housing, replacing the rotating depth-of-field indicator of the Zenobia C. A WALCON logo is embossed in the back leather and engraved above the viewfinder. The serial number is engraved behind the top housing, it seems that the two first digits indicate the year of production.
The Walcon Semi has a Kominar 75/3.5 front-cell focusing lens made by Nittō Kōgaku and a Copal B, 1–300 synchronized shutter with self-timer and PC socket. The aperture is set by an index above the shutter housing and the depth-of-field scale is on the shutter plate.
An advertisement dated August 1954 calls the camera "Walcon" while advertisements dated November 1954 and March 1955 call it "Walcon Semi". These advertisements are illustrated with stylish drawings of young women and in the two first ones, the Walcon is presented as a smart camera for ladies. The camera was priced ¥11,000, case included.
- ↑ No source has been found to confirm this, but it is obvious from pictures of the two cameras.
- ↑ An example observed in an online auction shows a faintly readable serial number that seems to begin with 54.
