This is a work in progress.

Nichidoku Shashinki Shōten and later Molta Gōshi-gaisha (the predecessors of Minolta) made a series of 6.5×9cm folding bed plate cameras from 1930 to the war. These are the Nifcaklapp (ニフカクラップ), Nifcasport (ニフカスポート), Sirius (シリウス), Arcadia (アルカデア), Eaton (イートン), Lomax (ロマックス) and Happy (ハッピー).

All have a metal body, a swivelling brilliant finder and a wireframe finder. They have double extension bellows driven by a wheel or worm screw placed on the photographer's right, and have a distance scale on the left. The various models differ by the focusing mechanism, the movement abilities and many other details.

This page only treats the folding bed models. See also the Nifca-Dox and the Minolta strut folders.

Nifca period

Nichidoku used the brand name "Nifca", coming from Nichidoku Foto Camera.[1] Nichi in Nichidoku means Japan, and it is certainly not coincidental that "Nifca" can also be read as Nippon Foto Camera. The Nifca range consisted of the Nifcaklapp and Nifcasport folding bed models, in addition to the Nifcarette 4×6.5 rollfilm camera and the Nifca-Dox strut folder. The Nifcaklapp and Nifcasport were both released in 1930.REF> "Hensen kamera ichiran-pyō", p.295 of Shashin Kōgyō no.77, also reproduced in Tanimura, p.7 of Camera Collectors' News no.116. This is repeated in Tanimura, p.1 of the same, Awano, p.13 of Kurashikku Kamera Senka no.12, Eimukku 735 Minolta, pp.131–2, Francesch, p.70, Scheibel, p.11, Sugiyama, items 1181 and 1183, McKeown, pp.671–2, Baird, p.39. </REF>

The Nifcaklapp

The Nifcaklapp[2] (ニフカクラップ) is the less advanced model. It has a focusing wheel turning on a longitudinal axis, certainly driving the front standard via a worm gear. The lens standard, made of pressed metal, is pulled out by two cylindrical posts, and gives no movement ability. The folding bed is held in closed position by two pins and is opened by pressing two buttons simultaneously, one at each side of the body. The frame finder has a round black eyepiece on the rear.

The Nifcaklapp appears in a full-page advertisement in Asahi Camera May 1930, with the English catch phrase "Nifcaklapp is better".[3] The format is mentioned as daimeishi (6.5×9cm), and the price is ¥39 with an Anastigmat 105/6.3 lens. The picture shows a camera with a dial-set Vario shutter and perhaps a Wekar-Anastigmat lens. The pulling posts at the bottom of the front standard are larger than on the other known pictures, the wireframe finder has no indent at the bottom, and the brilliant finder perhaps has a bubble level attached to the side.

The advertisement in Asahi Camera January 1931 presents the Nifca range but gives almost no detail.[4] It shows a different picture, which was reproduced in many later sources, including an early historical article by Chiyoda Kōgaku Seikō (predecessor of Minolta) in Shashin Kōgyō September 1958.[5] The camera differs from the previous one by minor details: the pulling posts at the bottom of the front standard are smaller and the wireframe has an indent at the bottom. The shutter is a dial-set Vario again, giving 25, 50, 100, B, T speeds. The lens is a 105mm f/6.3 made by Kenngott but its name is not legible; it has a number in the 503xx range.

The chronology compiled by Chiyoda Kōgaku Seikō (predecessor of Minolta) and published in Shashin Kōgyō September 1958 gives the following list of lens and shutter combinations:[6]

  • Wekar[7] Anastigmat 105/6.3 lens, Vario shutter (25–100);
  • Wekar Anastigmat 105/6.3 lens, Ibsor shutter (1–125);
  • Wekar Anastigmat 105/4.5 lens, Ibsor shutter (1–125);
  • Wekar Anastigmat 105/4.5 lens, Compur shutter (1–200).

Another source says that the price ranged from ¥39 to ¥69.[8]

One surviving camera is known with the plain wireframe (not indented) and perhaps the heavier pulling posts, certainly corresponding to an early example.[9] The available pictures are very small and do not allow to tell the lens and shutter equipment.

Another surviving camera is pictured in Sugiyama, with the indented wireframe and smaller pulling posts.[10] It has a dial-set Vario shutter and an Anastigmat Nifcaplan 105mm f/6.3 lens made by Kenngott.[11] The camera is very similar to the well-known picture described above, and the lens number is in the same 503xx range.

The Nifcasport

The Nifcasport (ニフカスポート)[12] is a more advanced model. It has the same body as the Nifcaklapp, with the same folding struts and the same closing mechanism. The focusing wheel has a more usual transverse disposition and the focusing rails are more precisely machined, certainly providing double extension. The front standard provides vertical and horizontal movement ability, driven by two knobs.[13]

The advertisement in Asahi Camera January 1931 shows a picture of a Nifcasport in extended position, but gives no other detail.[14] The camera has two cylindrical pulling posts, apparently similar to those of the late Nifcaklapp.

The best known picture is another retouched image, certainly used by the company for advertising purpose too. It appears in the September 1958 historical article, and in many later sources.[15] The camera differs from the previous one by some details: two handles replaced the pulling posts at the bottom of the front standard, and the wireframe has a different shape with a larger indent at the bottom to accommodate the two handles. The shutter is a dial-set Compur, and has a small plate marked Nifca Photo under the speed setting wheel. The lens is engraved Wekar-Anastigmat and the lens diameter probably indicates an aperture of f/4.5.

The official chronology published in September 1958 gives the following list of lens and shutter combinations:[16]

  • Wekar Anastigmat 105/4.5 lens, Ibsor shutter (1–125);
  • Wekar Anastigmat 105/4.5 lens, Compur shutter (1–200);
  • Nifcar Double Anastigmat 105/4.5 lens, Compur shutter (1–200).

One source says that the prices were ¥75, ¥85 and ¥90.[17]

The best known surviving example was belonging to the Minolta Gallery in the 1980s,[18] and is probably still the property of the Konica Minolta or Sony company. It is pictured in various sources, and is easily recognized because it is lacking the hinged wireframe and the front standard is missing a part, revealing the gearing mechanism for vertical movements.[19] It is easily recognized because it lacks the front wireframe of the sportsfinder (the rear eyepiece is still present). It has a Compur shutter (T, B, 1–250) and is said to have a Wekar f/4.5 lens.[20]

Another surviving example is known with the two pulling handles. It has yet another type of wireframe finder, with an indent at the bottom but no offset at the hinge.[21] The available pictures are very small and do not allow to tell the lens and shutter equipment.

Molta period

The company became Molta Gōshi-gaisha in 1931 and the name Nifca was consequently abandoned. The same year, a range of four folding bed models was introduced.[22]

The Sirius

Description

The Sirius (シリウス) is the simplest model. It seems to be a continuation of the Nifca Klapp. The main difference is the double extension bellows. The longitudinal focusing wheel is replaced by a worm screw and a bubble level is attached to the right of the brilliant finder. The shutter is a dial-set Koilos giving 25, 50, 100, B, T speeds.

Advertising

The Sirius was advertised with a Heliostar Anastigmat 105mm f/6.3 lens and three plate holders for ¥40.[23] It seems that the advertised camera has the same closing mechanism as the Nifca models, with a button on each side of the body.

Surviving examples

Two surviving examples are known, both with a Heliostar Anastigmat 105mm f/4.5 lens and a new closing mechanism: the folding bed is held in closed position by a spring attached to the body, engaging a slit in the focusing board. One is pictured in Sugiyama and Francesch.[24] The name Molta is engraved at the bottom of the lens standard, together with the serial number 7422x. A Nifca Photo nameplate is visible under the speed wheel. The camera was thus made during the Nifca-to-Molta transition period. The lens number is 7427x. The viewfinder eyepiece is similar to that mounted on the Nifca models.

The other example is pictured on this page. It has the body number 75692 and lens number 79355. The frame finder has a new type of eyepiece with a mostly rectangular shape. The camera has a film pack adapter, embossed Molta.

The Arcadia

The Arcadia (アルカディア) is a more advanced model. It has different focusing rails and a transversal focusing wheel. Horizontal and vertical movements are available. The shutter is a rim-set Lidex giving T, B, 1–200 speeds, made by the Molta company. This shutter challenges the Magna by Seikōsha for the title of first Japanese leaf shutter. The shutter plate is marked Lidex at the bottom and has the MTS logo on the right; it is sometimes marked Patents Pending at the top. The lens is a Heliostar Anastigmat München 105/4.5.[25] It is said that the price was ¥40.[26]

Two slightly different variants are known. One has the same folding struts as the previous models and a nearly rectangular wireframe.[27] The other has new folding struts with a more elaborate design and a new wireframe with a cut-off for the brilliant finder.[28]

The Eaton

The Eaton (イートン)[29] is reported by various sources but no picture has ever been observed.[30] It seems to be a version of the Arcadia with a Coronar 105/4.5 lens and a Crown A shutter giving T, B, 1–200 speeds. It is said that the price was ¥40, but possibly it was never sold.[31]

The Happy

Description

The Happy (ハッピー) is nearly identical to the late Arcadia variant, with the new folding struts and the cut-off in the wireframe for the brilliant finder. The main visible difference is the absence of horizontal movements and the new shape of the handles used to pull out the lens standard after opening. The serial number is engraved inside the back.

At least one example is known with a different finder eyepiece, consisting of a rectangle mounted on a small arm and a different wireframe (the latter is perhaps not original).[32]

The Happy has a Coronar Anastigmat 105mm f/4.5 lens, made by Asahi Kōgaku (later Pentax).[33] It was the first lens made by that company. The Happy and Eaton were among the first cameras entirely made in Japan, lens and shutter included. The shutter is a version of the Crown made by Molta itself, either a Crown B giving T, B, 5–200 speeds or a Crown S with an added self-timer.[34] On the early examples, the shutter plate is all black, engraved Patents-Nippon at the top and CROWN at the bottom with an MTS logo on the right. On later cameras, it has three metal strips on each side, is engraved PATENTS–NIPPON at the top and has no MTS logo. It has a larger aperture scale screwed to the bottom, inscribed with the name CROWN.

Advertising

The Happy was the longest-lived member of the family. Said to have been released in 1931, together with the Sirius, Arcadia and Eaton, it was advertised at least until 1939.[35]

The camera was distributed by Asanuma Shōkai. Advertisements dated April and July 1935[36] offered the model with Crown B shutter for ¥55 and the model with Crown S for ¥65. The leaflet reproduced in this page, dating about 1936, shows the same prices.

Notes

  1. See Francesch, p.17, and the Nifcarette page of the Konica Minolta website.
  2. The name appears as a single word in the advertisement in Asahi Camera August 1930, reproduced in Hagiya, p.9 of Kurashikku Kamera Senka no.12.
  3. Advertisement reproduced in Hagiya, p.9 of Kurashikku Kamera Senka no.12.
  4. Advertisement reproduced in Awano, p.6 of Kurashikku Kamera Senka no.12.
  5. Early historical article: Taniguchi, p.275 of Shashin Kōgyō no.77, also reproduced in Tanimura, p.8 of Camera Collectors' News no.116. Other sources displaying the same picture: Awano, p.13 of Kurashikku Kamera Senka no.12, Francesch, p.70, Scheibel, p.8, Lewis, p.49, McKeown, p.671, and Baird, p.39. The reproduction in Scheibel is by far the most legible.
  6. "Hensen kamera ichiran-pyō", p.295 of Shashin Kōgyō no.77, also reproduced in Tanimura, p.7 of Camera Collectors' News no.116. Francesch, p.71, gives a similar list but adds a fifth variant, with a Vario shutter and a Nifcaplan 105/6.3 lens, probably because he observed the surviving example having such combination. The mention of a Zeiss Anastigmat lens in McKeown, p.671, is surely a mistake.
  7. The names "Welka" in Lewis, p.45, and "Weker" in Sugiyama, item 1181, are mistakes.
  8. Scheibel, p.11.
  9. Example pictured in Eimukku 735 Minolta, pp.131–2.
  10. Sugiyama, item 1183.
  11. The lens engraving is faintly readable as W. Kenngott Anastigmat Nifcaplan 1:6.3 F=105mm, and the name Nifcaplan is confirmed by the description in Sugiyama.
  12. The katakana spelling ニフカスポート (Nifukasupōto) was used in the January 1931 advertisement in Asahi Camera, reproduced in Awano, p.6 of Kurashikku Kamera Senka no.12. However the later Japanese sources use the spelling ニフカスポーツ (Nifukasupōtsu), following the common spelling of the word "sport" (スポーツ, supōtsu).
  13. Francesch, p.71, mentions a spirit level but this is not visible in the pictures.
  14. Advertisement reproduced in Awano, p.6 of Kurashikku Kamera Senka no.12.
  15. Early historical article: Taniguchi, p.275 of Shashin Kōgyō no.77, also reproduced in Tanimura, p.8 of Camera Collectors' News no.116. Other sources displaying the same picture: Awano, p.13 of Kurashikku Kamera Senka no.12, Scheibel, p.8, McKeown, p.672, Baird, p.40, and this page at infocam.co.kr. The reproduction in Scheibel is by far the most legible.
  16. "Hensen kamera ichiran-pyō", p.295 of Shashin Kōgyō no.77, also reproduced in Tanimura, p.7 of Camera Collectors' News no.116. Francesch, p.71, gives the same list. The mention of a Zeiss Anastigmat lens in McKeown, p.672, is surely a mistake again.
  17. Scheibel, p.11.
  18. Sugiyama, item 1181.
  19. This camera is pictured in Francesch, p.70, and in Sugiyama, item 1181. A picture of this camera is in the 70th anniversary Minolta poster, reproduced in this page at Photoclub Alpha; poor reproductions of the same picture appear in this page of the Manual Minolta website, in this page of the Map Camera Museum, and in this page of the Kitamura Camera Museum.
  20. Shutter speeds and lens features: Sugiyama, item 1181. The focal length is given as 6.5cm, obviously by mistake.
  21. Example pictured in Eimukku 735 Minolta, pp.131–2.
  22. Date: Tanimura, p.1 of Camera Collectors' News no.116; Francesch, p.73; Scheibel, p.13; Sugiyama, items 1184–7; McKeown, p.672.
  23. Advertisement reproduced in this page of Takasaki Motohiro's camera site. The same advertisement is also reproduced in Scheibel, p.13. A poor copy of a similar advertisement has also been observed, listing the camera for ¥35.
  24. Sugiyama, item 1187, Francesch, p.72. The lens name "Helostar" in Francesch, p.73, is a mistake.
  25. The name "Helostar" in Francesch, p.73, and in McKeown, p.672, is a mistake.
  26. Scheibel, p.13, and this page of the JCII collection.
  27. This variant is pictured in Francesch, p.72, Sugiyama, item 1184, McKeown, p.672, and this page of the JCII website.
  28. This variant is pictured in Scheibel, p.12.
  29. It is extremely probable that no original document shows the Roman name. The name "Eaton" found in Francesch (pp.20 and 73), Scheibel (p.13) and Lewis (pp.45, 47 and 182) is likely a reconstitution from the katakana イートン. Another plausible Roman spelling is "Eton".
  30. Sources: Francesch, pp.20 and 73; Scheibel p.13; Tanimura, p.1 of Camera Collectors News no.116.
  31. Price: Scheibel, p.13.
  32. Example pictured in Francesch, p.72.
  33. McKeown, p.672, mentions Zeiss and Wekar Anastigmat lenses in Compur shutters on the earliest models, but this is unconfirmed.
  34. Sugiyama, item 1186, calls "Happy Hand Camera – Type S" the model with self-timer, but the advertisements only say "Happy". The camera presented by the same source as a regular "Happy Hand Camera" (item 1185) is a misidentified "Kokka".
  35. Date of the last advertisement listed in Kokusan kamera no rekishi, p.339.
  36. April 1935 published in Asahi Camera, reproduced in Tanimura, p.11 of Camera Collectors News no.118. July 1935 advertisement published in Asahi Camera, reproduced in Kokusan kamera no rekishi, p.83. July 1935 advertisement inserted in Toki no Nagare, a publication of Asanuma Shōkai, reproduced in Tanimura, p.19 of Kurashikku Kamera Senka no.12.
