The Semi Sport (セミスポーツ) is a Japanese 4.5×6 folding camera, made by Fujimoto from 1940 to the end of the war, and advertised as late as 1949. It is said that it was a renaming of the Semi Prince, released after the contract between the manufacturer Fujimoto and the distributor Fukada, owner of the name "Prince", was rescinded.[1]

Description Edit

The Semi Sport is a copy of the Ikonta, with the typical folding struts. It has a folding optical finder, whose opening is coupled to the release of the folding bed. The body release is placed to the left of the viewfinder, as seen by the photographer holding the camera horizontally. There is an advance key at the bottom right. The back is hinged to the left and the back latch consists of a long sliding bar. There is a single red window, at the bottom left of the back, protected by a vertically sliding cover.


The name Semi Sport is normally embossed in the front leather. A SEMI SPORT logo is embossed in the leather on the back and engraved on the folding struts.

The Semi Sport has the same body as its predecessor the Semi Prince III, made by the same manufacturer. The main difference is the new Rapidex shutter. At the same time, the company was also making the Semi Lucky III with a slightly smaller body.

The Rapidex shutter was made by Fujimoto itself, in its Mukogawa plant.[2] It gives T, B, 1–300 speeds and has a self-timer. The shutter plate has the name RAPIDEX inscribed at the bottom, three silver strips on each side and the FT logo of Fujimoto on the right — FT are the initials of Fujimoto Tōjirō (藤本藤次郎), the founder of the company.[3] The aperture scale is placed above the shutter housing.

The lenses were either imported lenses made by Schneider or Laack, or Japanese-made Lucky Anastigmat lenses, said to be supplied by Nishida Kōgaku.[4] The Semi Sport was one of the very last wartime Japanese cameras to have imported lenses, at a time when the imports of camera parts had stopped, perhaps because a large stock was bought at the time of the Semi Prince.

Prewar and wartime documents Edit

The Semi Sport was announced in mid-1940.[5] In an advertisement dated September 1940,[6] it is presented as similar to the Semi Prince (セミプリンスカメラと殆んど同様品) and available soon (近日発売). The picture of the advertisement already shows the Rapidex shutter.

In a December 1940 advertisement,[7] the camera is offered with a Radionar 75/4.5 lens, for ¥121. The official list of set prices compiled in October 1940 and published in January 1941 has a Semi Sport for ¥121, certainly corresponding to this version.[8]

In an advertisement dated September 1941,[9] the Semi Sport is offered in a choice of versions:

The official price list dated November 1941 has a Semi Sport I and a Semi Sport II, certainly corresponding to the cheap and expensive versions respectively.[10]

In January 1942,[11] the Xenar version was no longer offered and the prices rose to ¥188 for the Lucky f/3.5 version and ¥142 for the f/4.5 versions. At that time, the distributor was Taihō Shōkai (大宝商会).[12]

The government inquiry compiled in April 1943 mentions three versions of the Semi Sport I, with Lucky f/4.5, Regulyt f/4.5 or Isco f/4.5 and two versions of the Semi Sport II, with Lucky f/3.5 or Xenar f/4.5.[13]

Rangefinder conversions were offered in 1943 by Hakkōdō for the Semi Sport and various other copies of the Ikonta or Nettar (see this page).

Variations on actual examples Edit

Most examples of the Semi Sport observed so far have the Rapidex shutter and a Lucky Anastigmat 7.5cm f/3.5 lens, and at least two have the Rapidex and a Laack Regulyt 7.5cm f/4.5.[14]

Other non-standard variations have been observed. One example is known with a Super-Rapid shutter (T, B, 1–500) and a Lucky Anastigmat 7.5cm f/3.5 lens.[15] The lens has a very low serial number (no.00111) and the camera is perhaps an early prototype.

One example of the Semi Sport is known with a Compur-Rapid shutter (T, B, 1–500) and a Schneider Xenar 7.5cm f/4.5 lens.[16] This example belongs to the Fujimoto company, and it is perhaps a composite reusing the lens and shutter assembly of a Semi Prince.

Another example has been observed with a Compur-Rapid shutter and a four-element Lausar 7.5cm f/3.5 lens made by Tomioka.[17] This Lausar lens equipment is maybe original. A Lausar 7.5cm f/3.5 lens mounted on a Rapidex shutter, probably coming from a Semi Sport, is pictured in Sugiyama on a Liner Six postwar camera.[18]

At last, one example has been observed with a Rokuoh-Sha Hexar Ser. II 75mm f/3.5 lens mounted on a leaf shutter with only three speed settings on the rim: 100, 200 and 400;[19] a similar lens and shutter assembly has been observed on a GSK-99 aerial camera, and the example found on the Semi Sport certainly comes from one such camera.

One source also mentions an Isco and Prontor II combination but this is unconfirmed.[20]

After the war Edit

The Semi Sport was offered again in 1949.[21] It appears in a September 1949 advertisement,[22] together with a Lucky enlarger, also made by Fujimoto in the prewar and wartime period. The lens is mentioned as a Texar 75/3.5, a name which is otherwise unknown. In the advertisement, the only company name is Nihon Kōki Kōgyō K.K. (日本光機工業株式会社). The pictured camera shows no visible change from the prewar and wartime model. The postwar Semi Sport was probably made from remaining stocks of parts, and it was maybe assembled by Nihon Kōki Kōgyō. (Fujimoto had ceased activity in 1945 and would not be reactivated until 1950.)[23] The company was certainly conscious that the camera was a little outdated, and the advertising sentence is: "Based on an experience of several years, now available again!" (多年の経験に基いてここに再登場).

The two examples pictured in Sugiyama, items 1249–50, are called "Semi Sport I", but item 1250 has a Lucky f/3.5 lens and corresponds to the "Semi Sport II". McKeown, p.332, calls the camera "Semi Sport I" after Sugiyama.

  20. Tanaka, p.77 of Kurashikku Kamera Senka no.8, says that the Semi Sport was released in 1940 with an Isco lens and Prontor II shutter, and that the Rapidex shutter was introduced in 1941. The second affirmation is wrong.
