The Baby Minolta (ベビー・ミノルタ) is a Japanese camera taking 4×6.5cm pictures on 127 film, made by Molta then Chiyoda (later Minolta) between 1935–6 and 1940.[1]

Description

The Baby Minolta is a simpler camera than the Minolta Vest released earlier. It has a bakelite body covered with leather or leatherette and a bakelite telescopic tube supporting the lens and shutter assembly. There is a folding frame finder in the middle of the top plate, indicating the field of view for both 4×6.5 and 3×4 formats. The advance knob is at the left end of the top plate and film advance is controlled via two uncovered red windows in the back.

The film plane is curved to compensate some of the lens aberrations. To load the film, the top plate is removed together with the spool holders and exposure chamber. It is locked into place by a lever placed at the bottom. The bakelite is recessed around this lever and the words OPEN and CLOSE are moulded, together with the MTS logo, TRADE MARK and MADE IN JAPAN.

The lens is a fixed-focus cemented doublet.[2] It wears no marking and its focal length is unknown, but probably 75 or 80mm. It has no aperture setting and its maximal aperture is not mentioned in the advertisements. Some sources say that it is a Coronar 80/8[3] but the use of the Coronar name (used for a triplet design) is very unlikely.

The shutter gives 25, 50, 100, B speeds set on a dial at the top. It is everset and the release lever is attached to the shutter plate.

It is said that about 2,000 examples of the Baby Minolta were produced per month, accounting for a total production of 50,000 examples.[4]

Evolution

First variant

The first variant has small indexes in the finder to indicate the field of view for 3×4cm exposures. There is a metal advance knob with a low profile and either a flat top or concentric rings.[5] The shutter plate is marked PATENTS PENDING at the top and BABY MINOLTA at the bottom. It has the MTS logo of the Molta company on the right and a chain of small circles drawing a decorative pattern on the contour.

The camera was first featured in the new products column of the April 1936 issue of Asahi Camera.[6] The first variant appears in advertisements dated April, May and August 1937 and January 1938.[7] The price was ¥9.50 in 1937 (case ¥2 extra) and ¥11 in 1938.


Second variant

The second variant has two bars in the finder for 3×4 format. The metal advance knob has a higher profile and a recessed centre and the shutter plate is marked PATENTS NIPPON instead of PATENTS PENDING.


Third variant

The third variant has a new shutter plate design with three stripes on each side. It is marked PATENTS NIPPON at the top and BABY MINOLTA at the bottom, and it does not have the MTS logo.


Fourth variant

The fourth variant has a black bakelite advance knob instead of the metal knob. It appears in an advertisement dated December 1939,[8] where it was offered for ¥12. An advertisement in English depicting the third or fourth variant is reproduced in Francesch.[9] This may indicate that the company tried to export the camera.

The Baby Minolta was listed in the official price list compiled in October 1940, for ¥10.[10]


Case

Two types of cases are known. One has the MTS logo and probably corresponds to the first and second variants. The other is embossed Baby Minolta and probably corresponds to the third and fourth variants.


Notes

  1. Dates: advertisements listed in Kokusan kamera no rekishi, p. 342. Many sources, including Francesch, p. 252, Scheibel, p. 21, Lewis, pp. 52–3, McKeown, p. 673, Sugiyama, item 4056, and Awano, p. 16 of Kurashikku Kamera Senka no. 12, all give 1935 as the release date, but many of them make other mistakes about the early Minolta release dates and Kokusan kamera no rekishi is considered more reliable.
  2. A catalogue dated October 1941 by Asanuma gives the lens scheme, showing a cemented doublet. The word used in the advertsements is tangyoku (単玉), literally meaning "single lens" but used for cemented doublets as well: see the 1936 leaflet reproduced in this page and the August 1937 advertisement reproduced in Kokusan kamera no rekishi, p. 97.
  3. Francesch, p. 252. McKeown, p. 672, says Coronar Anastigmat and Scheibel, p. 21, says Achromat-Coronar.
  4. 2,000 examples per month according to Tashima Gizō (son of Tashima Kazuo, founder of the company), interviewed by Saeki Kakugorō on p. 78 of Kurashikku Kamera Senka no. 12. 50,000 total production: Awano, p. 7 of the same magazine.
  5. Flat top: examples pictured in Francesch, p. 252, and in Sugiyama, item 4056. Concentric rings: example pictured in this page.
  6. Kokusan kamera no rekishi, p. 342.
  7. April 1937: published in Asahi Camera, reproduced in Kokusan kamera no rekishi, p. 98.
    May 1937: advertisement published in the 9 May 1937 issue of Sunday Mainichi, reproduced in the Gochamaze website.
    August 1937: published in Asahi Camera, reproduced in Kokusan kamera no rekishi, p. 97.
    January 1938: published in Asahi Camera, reproduced in Tanimura, p. 15 of Camera Collectors' News no. 118.
    The same version is still pictured in an advertisement published in Shashin Shinpō reportedly dated January 1940, reproduced in Hagiya, p. 10 of Kurashikku Kamera Senka no. 12. Perhaps there is a date mistake, or the company was using old pictures in the advertisements.
