The Semi Prux (セミ・プラックス) is a Japanese 4.5×6 folding camera. It was made from 1938 by Proud-sha and perhaps Miyoshi Kōgaku, two companies which were related and certainly merged after some time. Its successor was the Roavic by Miyoshi.

Description

The Semi Prux is a horizontal folder. Its general design and folding struts are copied from the Duo Six-20 by Kodak AG. There is a folding optical finder in the middle of the top plate, with the folding bed release immediately to the right. The advance key is at the top left; it has an angulous shape and is hinged on an octogonal knob. The back is hinged to the right and has two red windows near the bottom, protected by a horizontally sliding common cover. The name SEMI PRUX is embossed in the front leather.

Original documents

The Semi Prux was featured in the November 1938 and February 1939 issues of Asahi Camera, and it was advertised in 1939 and 1940.[1] In advertisements dated May and June 1939 and February 1940,[2] the camera was offered in two versions:

  • U.L.L. f/4.5 lens, Licht shutter by Seikōsha (¥65);
  • U.L.L. f/3.5 lens, Prux shutter, T, B, 5–200 speeds (¥80).

The Semi Prux was presented along with the Semi Proud, as "the two favourite Japan-made cameras" or "the two authorities on Japan-made cameras".[3] The two distributors were Yamashita Yūjirō Shōten of Tokyo and Fukada Shōkai of Osaka. The June 1939 and February 1940 advertisements also show the two company names Proud-sha and Miyoshi Kōgaku. The cheapest version was offered alone in an October 1939 advertisement by Fukada,[4] together with Doris and Prince models.

Actual examples

Only one surviving example of the Semi Prux has been observed.[5] It has a Licht shutter giving 25, 50, 100, B, T speeds, of the late version with the "needle self-timer". The lens is engraved U.L.L. Anastigmat 1:4.5 f=7.5cm No.10254.
