The Baby Pearl is a Japanese 3×4 folding camera, made from 1934 to 1950 by Konishiroku (predecessor of Konica).[1] It takes 127 roll film.

General description Edit

Body Edit

The Baby Pearl is a vertical folder inspired by the Zeiss Ikon Baby Ikonta, but not a dead copy. It has incurved struts and a folding optical finder. The body edges are either black or chrome finished. The name BABY PEARL is embossed in the leather covering at the front.

The back is hinged to the left and is locked by a sliding bar on the right — as seen by the photographer holding the camera horizontally. The film is advanced by a knob at the bottom right, and there are two red windows in the back to control its position. On most cameras, the main release is on the shutter casing and the folding bed release is close to the advance knob, but the last postwar examples have a body release and bed opening button symmetrically placed around the viewfinder (see below).

The dimensions are about 100×70×30mm, and the weight is little more than 300g.[2]

Shutter Edit

The shutter is a Rox (B, 25, 50, 100), made by the company itself. The speed is selected by an index at the top of the shutter casing. The Rox shutter is everset on most cameras, but the last examples with body release have a cocking lever.

The shutter plate is always marked ROX at the top and has the manufacturer's name at the bottom. Its design was changed on various occasions: it is plain black on the earliest examples, then black with the aperture scale inscribed on a chrome rim, then a pair of chrome lines was added on either side of the lens (see the evolution below).

The manufacturer's name at the bottom appears as Rokuoh-sha or Konishiroku. The production of the Rox shutter started in the Rokuoh-sha factory, but from 1936 onwards it was actually transferred to Yamamoto Kōjō, a subcontractor of Konishiroku.[3] It is not known if Yamamoto Kōjō acted as a subcontractor until the end, or if Konishiroku took over the production again at some time.

Lens Edit

Four different lenses were mounted on the Baby Pearl, all with 50mm focal length and focusing by turning the front element. The Optor f/6.3 and f/4.5 lenses are triplets designed by Konishiroku; they were reputedly manufactured by Asahi Kōgaku (predecessor of Pentax), but their production was perhaps taken back by Konishiroku at some time (see below).[4] The Hexar Ser.1 f/4.5 is a four-element lens, designed and made by Konishiroku, and an f/3.8 version was introduced in June 1937.[5]

The lens bezel is black on the early cameras, and chrome on the later ones. The Optor and Hexar Ser.1 lenses made until the end of the war have Rokuoh-sha markings. The Hexar lenses made after 1945 have Konishiroku markings, without "Ser.1" except for the earliest ones. Lens coating was applied on the last model with body release.[6]

Rokuoh-sha and Konishiroku markings Edit

The manufacturer's name appears — either as Rokuoh-sha or Konishiroku — on the lens rim, at the bottom of the shutter face, and sometimes stamped on the leather covering of the back. "Rokuoh-sha" was the name of the manufacturing branch of the Konishiroku company until World War II. It seems that this name came into disuse after the main company was reorganized as Konishiroku Shashin Kōgyō in April 1943. The civilian production was probably stopped around that time, and it seems fair to assume that all the cameras with Konishiroku markings were made after 1945.[7]

Evolution Edit

Original model, knurled advance knob Edit

The Baby Pearl was introduced in May 1934.[8] The original model is mainly recognized by the knurled advance knob, inspired by that of contemporary Voigtländer cameras. The two red windows are uncovered, and have a characteristic shape with a round indent allowing to see the number before it comes into the proper position.

The viewfinder is all black and has a rectangular eyepiece. At least some examples have a hairline cross sight on the viewfinder's front window.[9] Inside the body, it is said that the pressure plate does not cover the full exposure chamber, but only a small portion on the supply side.[10]

The shutter plate is plain black and has the aperture scale engraved in white letters, with a red dot between 8 and 11. The lens bezel is black with white markings, such as Rokuoh-sha N°xxxx Optor 1:6.3 f=50m.m.

One of the earliest advertisements, dated May 1934, shows this model and already lists three lens options:[11]

Cumulative changes and regular black model Edit

New metal knob Edit

At the beginning of its production run, the Baby Pearl went through a number of minor changes. After a few months,[14] the advance knob was replaced by a larger one with fine mills. (At least one example is known with this knob and the older shutter plate.)[15]

New shutter rim Edit

Soon after, the shutter plate received a nickel rim, with the aperture scale engraved in black letters and the same red dot between 8 and 11.[16] The nickel rim makes the shutter look like the modern rim-set units, but it is actually fixed. On some examples, the hump-shaped release lever was replaced by a triangular part.

Smaller red windows Edit

The next significant change was the fitting of smaller rectangular red windows, which would become typical of the Konishiroku rollfilm cameras. At the beginning, these red windows were uncovered.[17] This version with the small uncovered windows is very uncommon, and is only known from Masaki's article.

Bakelite knob, removable pressure plate Edit

Very soon, the advance knob was replaced again. At least one example is known with a different metal knob, whose design is similar to the knob mounted on Pearlette cameras from 1933 to 1935.[18] The definitive model has a black bakelite part instead.[19] It is said that the next change was the introduction of a removable pressure plate, covering the whole exposure chamber.[20]

Covered red windows Edit

The last cumulative change was the addition of red window covers, controlled by a single slider.[21] These were certainly already fitted when Rokuoh-sha introduced the Sakura Pan F panchromatic film in January 1936.[22] After that, the camera's features reached a stable state, resulting in the regular black model, produced until late 1937.

Chrome model, new shutter face Edit

The chrome model was announced in January 1938.[23] The body edges were metal finished, and the smaller metal parts were plated with chrome instead of nickel. The viewfinder's rear part was modified with chrome plating and a circular eyepiece.

A few transitional examples were made with the chrome finish and the older shutter plate,[24] before it was replaced by a newer machine-stamped plate, with metal strips on both sides of the lens. At first, the new shutter face was nickel-finished and the lens bezel remained black with white engravings.[25] Then the shutter parts became chrome-finished and the lens bezel was replaced by a chrome rim with black engravings.[26]

The Optor f/6.3 lens option was sold in limited numbers on the chrome-finished model, and has always been observed with a black bezel.[27]

It is said that a special edition of the chrome model was made with red or green leather covering, called the Lady's Pearl,[28] but no surviving example has yet been observed.

Luxury f/3.8 version Edit

In June 1937,[29] some months before the introduction of the chrome model, a luxury version was released with a Hexar f/3.8 lens. The announce column in Sakura no Kuni shows the price of ¥55.[30] This version is very uncommon, and was certainly produced in limited numbers.

At least one example, pictured in articles by Awano and Masaki, is known with a black bezel, marked Hexar Ser.1 with a low three-digit serial number.[31] It has the older black body and viewfinder, combined with the new shutter face described above. This might indicate that the new shutter plate was first introduced on the luxury model, before the introduction of the chrome model,[32] or that this particular camera is a transitional example assembled with mismatched parts.

A couple other examples, pictured in Sugiyama and in Awano's article, have a chrome bezel, marked Hexar Ser.II with a four-digit serial number.[33] (The new lens name perhaps reflects a change in the optical formula.) They have the chrome body and viewfinder, and the new shutter face.

Documents dated 1939–40 Edit

It seems that the pictures used in contemporary advertisements were outdated and do not reflect the actual version sold at the time. Advertisements in the January, May and September 1939 issues of Asahi Camera use the same picture, showing a very early camera, with the earliest type of shutter plate and the old viewfinder eyepiece.[34] The picture was retouched for the May issue only, pretending that the camera has chrome body edges and a chrome viewfinder. The January advertisement lists all four lens options:

The May and September advertisements only list the Optor lenses.

The official list of set prices compiled in October 1940 and published in January 1941 lists three versions, called "Baby Pearl I" (¥28), "Baby Pearl II" (¥48) and "Baby Pearl III" (¥65).[36] These probably correspond to the f/6.3, f/4.5 and f/3.8 lenses respectively. (The rigid system of set prices does not distinguish between the three-element Optor and the four-element Hexar.)

Semi-chrome model Edit

At some time, the chrome finish was abandoned and the camera edges were covered with black lacquer again. The transition perhaps occurred in the late 1930s or early 1940s (though at least some cameras were surely made after 1945, see below).[37]

This new generation of black cameras is sometimes called semi-chrome by today's collectors.[38] All have the new chrome-plated viewfinder with round eyepiece and the new shutter plate design with chrome-finished parts. (None has the transitional nickel-finished shutter plate, probably indicating that the production of black lacquered cameras was completely displaced for some time by the chrome model.)

All the semi-chrome cameras have a chrome lens bezel,[39] except for those with the Optor f/6.3 which retained the black bezel.[40] This lens option is very uncommon and was probably withdrawn soon after the introduction of semi-chrome finish.

The last wartime mention of the camera is in the April 1943 government inquiry on Japanese camera production (with no picture).[41] This document lists only two versions, with the Optor f/4.5 and Hexar f/4.5 lens — the latter is called "Baby Pearl II". In this document, the Optor lens is registered as made by Konishiroku too, perhaps indicating that its manufacture was taken back from Asahi Kōgaku at some time.[42]

At least some semi-chrome cameras have the words ROKUOH–SHA and MADE IN JAPAN embossed in the leather covering of the back door, near the hinge.[43] The Rokuoh-sha name was apparently dropped in 1943, and these pieces of leather covering were certainly stamped before the end of the war, though an indication of origin in English language may look unnatural on a Japanese wartime product.

Postwar period and Konishiroku markings Edit

The production of the Baby Pearl was resumed in 1945 in the Yodobashi plant,[44] initially drawing on the stock of spare parts.[45] It is said that the camera was released in October 1945 with the Optor f/4.5 and in March 1946 with the Hexar f/4.5.[46]

Few postwar documents are known to mention the Baby Pearl. A single advertisement is reported, in the October 1946 issue of Ars Camera.[47] The price was set on 17 June 1946 by the Japanese Ministry of Finance, to ¥910 for the version with Optor and to ¥960 for the version with Hexar.[48] By September 1947, the set price for the Hexar version was ¥2,440, reflecting the high inflation of the time.[49] The camera is mentioned again in an article in Photo Art December 1949 on Japanese camera production, which lists the Optor f/4.5 and Hexar f/4.5 lenses, and gives the price category as "¥5,000 to ¥10,000".[50]

As said above, it seems that all the cameras with Konishiroku markings were made in the postwar period. None of these has yet been observed with an Optor lens. This perhaps means that all the cameras assembled after 1945 with the Optor lens used old parts marked Rokuoh-sha, making them indistinguishable from the wartime model. However, a few contemporary Semi Pearl are known with an Optor lens marked Konishiroku, and similar Baby Pearl might exist too.

The earliest identifiable postwar cameras have an intermediate form of lens marking: Konishiroku N°xxxxx Hexar Ser.1 1:4.5 f=50m.m, and still have the Rokuoh-sha marking on the shutter.[51] Some still display the ROKUOH–SHA and MADE IN JAPAN embossings on the back, and some are known to have the same removable pressure plate as the prewar and wartime models. These Baby Pearl were possibly assembled from stocks of camera bodies, complete with shutter and leather covering, and only lacking a lens.

The Rokuoh-sha markings were gradually phased out. A combination of the Konishiroku and Hexar Ser.1 lens markings, together with a Konishiroku marking on the shutter face, is visible in the picture of a Baby Pearl in Photo Art December 1949, showing a camera that was perhaps assembled a few years earlier.[52]

Later examples have a shorter lens marking: Konishiroku N°xxxxx Hexar 1:4.5 f=50mm, paired with the name Konishiroku on the shutter plate.[53] It seems that the embossings on the back cover became KONISHIROKU and MADE IN JAPAN (stamped in relief) around the same time.[54] The removable pressure plate was also replaced by a fixed pressure plate attached to the back door, a sure indication that the company was no longer relying on wartime stocks only, but was also making new body parts.[55]

Body release Edit

Towards the end of the production, the Baby Pearl was modified again by the addition of a body release and lens coating.[56] The body release was added on the viewfinder's left, and the folding bed release was moved to a new position, on the other side of the viewfinder. The former release lever was replaced by a shutter cocking lever, shaped exactly the same. The bakelite advance knob was replaced by a larger metal part. (One isolated example has been observed with an advance key instead of the metal knob, but it is not known if this fitting is original or not.)[57] All the examples known so far have the Hexar f/4.5 lens with the newer markings and a number in the 6xxxx range.[58] At least some cameras have MADE IN OCCUPIED JAPAN embossed in the back,[59] instead of MADE IN JAPAN found on earlier versions.

The production of the Baby Pearl was stopped in late 1950.[60] It is said that about 12,000 units were made in the postwar period.[61]

Accessory 35mm adapter Edit

An adapter was supplied by a third-party manufacturer to load the Baby Pearl with 35mm film, consisting of an exposure mask, a pressure plate, and special spools in reloadable cassettes.[62]

Notes Edit

  1. Dates: Miyazaki, pp.10–3. The Baby Pearl has the odd distinction of being the only camera to be named in John W. Dower's Embracing Defeat: Japan in the Wake of World War II (New York: Norton, 1999). Dower suggests that it was a postwar innovation and says that it was aimed at GI buyers. Most postwar examples would indeed have gone to GIs (as was true for most models of camera in the late forties, when most of the Japanese population was desperately poor); however, the design was prewar and the "Pearl" name goes all the way back to 1909.

  21. Covered red windows, engraved shutter plate: example pictured in this page of the Yamada Camera Museum. This is also reported for picture no.8 in Masaki, p.46 of Kurashikku Kamera Senka no.10.

One isolated camera has been observed with the black-finished body and viewfinder, red window covers and the new chrome-finished shutter plate and lens bezel, probably because its lens and shutter unit was swapped at some time.
  22. This is suggested by Masaki, p.46 of Kurashikku Kamera Senka no.10. Kokusan kamera no rekishi, p.338, says that the camera was modified in 1935. Tanaka, p.59 of Kurashikku Kamera Senka no.8, says that the new features were introduced in January 1935, and transitional examples were made after that date, mixing old and new parts, but this seems dubious.

Masaki, p.112 of Kurashikku Kamera Senka no.4, and Tanaka, p.60 of Kurashikku Kamera Senka no.8, say that the production began in October 1945, and Miyazaki, p.12, says that the sales really began in March 1946.
