| + | For two decades, [[Olympus]] (or its predecessor [[Olympus|Takachiho]]) produced folding cameras for 120 film. These are the 4.5×6 [[Semi Olympus]] and [[Semi Olympus II]] and the 6×6 and 4.5×6 dual-format [[Olympus Six]] and [[Olympus Chrome Six]]. All of them are now described in separate pages. |

| − | For two decades, [[Olympus]] (or its predecessor Takachiho) produced folding cameras for 120 film. The first models were the 4.5×6 format Semi Olympus. Then followed the 6×6 and 4.5×6 dual-format Olympus Six made before, during, and immediately after the war. From 1948, improved models were sold as the Olympus Chrome Six. | |
| − | | |
| − | == Semi Olympus ==
| |
| − | The first camera made by Takachiho (later [[Olympus]]) was the '''Semi Olympus''' (セミ・オリンパス, ''semi orinpasu'').
| |
| − | | |
| − | === Description ===
| |
| − | The Semi Olympus is a 4.5×6cm folding camera for 16 exposures on 120 film, with a vertical folding bed and a folding optical finder. The body is a copy of the German [[Baldax]] (the large model for #0 shutter size). It was made by the Japanese company [[Proud]], and it is the same as the body of the prewar [[Semi Proud]].<REF> Sakurai Eiichi, pp. 64–5 of {{KKS}} no. 20, Hagiya, p. 14 of the same magazine, Hibi, p. 62 of {{KKS}} no. 8 and other sources. Francesch, pp. 23 and 56–7, says that the body was made by the German company [[Plaubel]], but this is a confusion. </REF>

| − | The advance knob is at the bottom right, as seen by the photographer holding the camera horizontally. The film advance is controlled by red windows. The back is hinged to the left and the back latch is covered by a leather handle. The folding bed release is to the right of the viewfinder and there is no body release. The name ''OLYMPUS'' is embossed in the front leather.
| |
| − | | |
| − | The lens is a four-element [[Zuiko]] 75mm f/4.5, focused by turning the front element. It was the first serial produced camera lens from the future Olympus company. The lens rim is engraved ''Takatiho Tôkyô Zuikô 1:4.5 f=75mm. No.1xxx'',<REF> "Takatiho" and "Takachiho" are alternative romanizations of the same name. The pronunciation has the "chi" of "chilly", not the "ti" of "tinfoil". </REF> except on one composite example described below.
| |
| − | | |
| − | === Origin ===
| |
| − | Takachiho had developed camera lenses from 1934. The first results were tried in mid 1936, among which were a 105/4.5 and a 75/4.5, both with four elements in three groups, designed by Pr. Miyata <!-- Shōichi or Hisaichi -->(宮田尚一) under the supervision of Mr Suzuki (鈴木).<REF> 105/4.5 and 75/4.5: Hagiya, p. 13 of {{KKS}} no. 20. Pr. Miyata and Mr Suzuki: Sakurai Eiichi, p. 64 of the same magazine. </REF> Two lens elements out of four were made of Japanese lens glass, supplied by the Osaka Industrial Research Institute (大阪工業試験所, Ōsaka Kōgyō Shikensho).<REF> Hagiya, p. 13 of {{KKS}} no. 20, about the 75/4.5. </REF> Various camera manufacturers were approached but the lenses did not sell. Miyazaki Shizuma (宮崎静馬), founder of [[Proud|Proud-sha]], talked to Mr Kura (内蔵), in charge of commercial planning at Takachiho, and suggested making a camera around the Zuiko lens and selling it under the "Olympus" brand, already registered by Takachiho for microscopes.<REF> Sakurai Eiichi, p. 64 of {{KKS}} no. 20. </REF> He offered to supply the camera bodies, the same as for the [[Semi Proud]], and insisted on adopting the [[Compur]] shutter, to make the camera easier to sell.<REF> Sakurai Eiichi, pp. 64–5 of {{KKS}} no. 20. </REF> According to Sakurai Eiichi, only one lot was made before the shutter imports stopped;<REF> Sakurai Eiichi, p. 65 of {{KKS}} no. 20. </REF> he does not state the reason for this, although it might have been the outbreak of war with China.

| − | === Documents ===
| |
| − | Today the Semi Olympus is usually called "Semi Olympus I", but it seems that this designation was not used at the time it was sold. The camera was featured in a column of the March 1937 issue of ''[[Camera Club]]''; this is the oldest mention reported in Japanese photographic magazines.<REF> {{Kokusan}}, p. 335. </REF>
| |
| − | | |
| − | The Semi Olympus was advertised in the June 1937 issue of ''[[Asahi Camera]]'' and in the July 1937 issue of ''[[Ars Camera]]''.<REF> Hibi, p. 63 of {{KKS}} no. 8. </REF> The advertisement in ''Asahi Camera'' was placed by the distributor [[Yamashita|Yamashita Yūjirō Shōten]].<REF> Advertisement on p. A65 of the magazine; reproduced in {{Kokusan}}, p. 62, in Hibi, p. 62 of {{KKS}} no. 8 and in Hagiya, p. 10 of {{KKS}} no. 20. (From the July issue, Takachiho used its one page in ''Asahi Camera'' to advertise the [[Olympus Standard]].)</REF> It mentions two versions, one with a [[Rulex|Rulex A]] shutter (1–200, T, B) made by [[Neumann & Heilemann]], priced {{yen|78|1937}}, the other with an [[Compur|Auto-Compur]] shutter (1–250, T, B) priced {{yen|98|1937}}, with a supplement of ¥5 for the case. (Some sources say that the camera was priced at ¥105, but no original document has yet been found to confirm this.)<REF> Price of ¥105: Sakurai Eiichi, p. 65 of {{KKS}} no. 20, Hagiya, p. 14 of the same magazine. Even the testimony of Sakurai is not completely certain: such a minor detail might have been remembered wrongly. </REF> The ''Asahi Camera'' advertisement states that the camera's dimensions are 13×7.5×4 cm, and that it weighs 540g.
| |
| − | | |
| − | === Release date ===
| |
| − | Most sources say that the camera was first sold in 1936; some specify September.<REF> September 1936: Sakai, p. 7 of {{KKS}} no. 20. This source seems extremely accurate on all points. </REF> No original document has yet been found to support this date, six months earlier than the cover date of the first Japanese magazine in which it is known to appear. The testimony of Sakurai Eiichi consulted so far does not explicitly support the 1936 release year either.<REF> "Zadankai: Orinpasu no michi", pp. 64–71 of {{KKS}} no. 20. </REF> On the contrary, he describes a number of events which necessarily took place between the final lens tests in June or July 1936<REF> June 1936: Francesch, p. 20. July 1936: Sakai, p. 7 of {{KKS}} no. 20. </REF> and the release of the camera: the attempts to sell the Zuiko lenses alone, the contacts with Proud, the procurement of shutters and finally the contacts with a distributor. However, Matsuzaki Sōichirō (松崎惣一郎), Sakurai's brother-in-law, remembers that he was shown an example of the Semi Olympus around 1936.<REF> Matsuzaki, p. 28 of {{KKS}} no. 76. He says that he was shown the camera at about the same time Sakurai married his sister. </REF>
| |
| − | | |
| − | All this does not mean that the 1936 release date is mistaken, only that it is unsure.<REF> The fact that it is stated in the official history of [[Olympus]] obviously does not constitute a proof in itself. For example the company [[Minolta]] made major mistakes in the release dates of its prewar models (see the [[Semi Minolta]] article) and in the name of its earliest camera (see the [[Nifcarette]] article). </REF> The first sales were certainly on a very small scale, and may have occurred months before the first mention in photographic magazines. Another theory would be that the September 1936 date is that of the completion of the first experimental cameras rather than that of the sales debut.
| |
| − | | |
| − | === Surviving examples ===
| |
| − | The '''version with Compur shutter''' is usually said to be the earliest one. Two surviving examples are known, with lens no. 1048 and 1142.<REF> Lens no. 1048: example pictured in Francesch, p. 56, in {{McKeown}}, p. 747 and in {{Sugiyama}}, item 1213. Lens no. 1142: example owned by John Foster and pictured in [http://www.biofos.com/coll/subcoll/folder.html this page of his website]. </REF> It is very plausible that the serial number sequence began at 1000: this was a very common practice at the time among Japanese optical companies.<REF> It would be extremely difficult to prove this assertion though, unless the lens registries are still held by the Olympus company. </REF> The Compur shutter plate has the ''FD'' logo on the right (for <U>F</U>riedrich <U>D</U>eckel), the usual ''COMPUR'' marking at the bottom and a small plate marked ''OLYMPUS'' screwed at the top, at the place usually provided in the Compur rim-set shutters to display the camera maker's name. The aperture scale goes from 4.5 to 22 and is screwed to the bottom. The shutter itself gives T, B, 1–250 speeds, has a self-timer and a screw to attach a soft release. There is an arm in front of the shutter plate, linked to the Compur shutter. It is tripped by the photographer's right hand and acts as a release. The Compur was designed for a body release, and without this linkage the position of the release lever would have been impractical because of the folding struts. The same device, with an exactly similar part, is known on some examples of the [[Semi Proud]] with Compur shutter.<REF> Example of the Semi Proud pictured in Hibi, p. 62 of {{KKS}} no. 8, and example pictured in an advertisement dated February 1938 reproduced in {{Kokusan}}, p. 89. </REF> This is perhaps an indication that the Compur were supplied by [[Proud|Proud-sha]].
| |
| − | | |
| − | The '''version with Rulex shutter''' is generally unknown to Western collectors. However one surviving example has recently surfaced (pictured in this page), with lens no. 1137. The Rulex gives 1–200, B, T speeds and has the early type of shutter plate, as described in the [[Rulex]] page. It has an ''OLYMPUS'' nameplate screwed to the top of the shutter plate, the same as on the Compur shutter. The aperture scale looks the same as on the Compur.

| |
| − | | |
| − | It is usually said that there is a later '''version with Koho shutter'''. The [[Koho]] shutter was made by [[Olympus|Takachiho]] itself and was mounted on the Semi Olympus II and later on the Olympus Six. It was first announced for the Semi Olympus II under the name "Laurel". The existence of a Semi Olympus with Koho shutter would imply a sales overlap with the Semi Olympus II. No advertisement for this version is known, and none of the advertisements for the Semi Olympus II mentions the original model.
| |
| − | | |
| − | Two surviving examples of the Semi Olympus actually exist with a Koho shutter. One has lens no. 1078 and a shutter giving 1–200, B, T speeds.<REF> Example pictured in Hibi, pp. 62 and 63 of {{KKS}} no. 8, in ''Orinpasu-ten'' (cover, pp. 3 and 4) and in ''Omoide no supuringu-kamera-ten, p. 23. </REF> The lens number is close to the other numbers mentioned above. However the shutter version is strange: the Koho was first produced for the Semi Olympus II with 1/150 top speed, and the switch to 1/200 top speed did not occur before at least late 1939.<REF> The 1/150 top speed is still mentioned in the advertisement for the Semi Olympus II published in ''[[Asahi Camera]]'' October 1939, reproduced in [http://www.warbirds.jp/heiki/31000.htm this page of the Heiki Seikatsu website]. </REF>
| |
| − | | |
| − | The other example has lens no. 6358 and is held at the Olympus gallery.<REF> Example pictured in Francesch, p. 57, in {{McKeown}}, p. 747, in {{Sugiyama}}, item 1214, in [http://www.olympus-global.com/en/corc/history/camera/ this page of the Olympus corporate site] and in many other sources. </REF> It has a Koho shutter giving 1–150, B, T speeds. This time the lens number is problematic: the other four cameras are in the 10xx and 11xx range, the lowest lens number observed so far on a Semi Olympus II is no. 144x in an advertisement dated May 1938 (see below) and no. 2001 on an actual example, and the lens no. 7157 has been observed on an Olympus Six, dated about 1940.<REF> Semi Olympus II with lens no. 144x: advertisement in ''[[Asahi Camera]]'' May 1938, p. A52, reproduced in Hagiya, p. 62 of {{KKS}} no. 8. — Semi Olympus II with lens no. 2001: example held at the Olympus gallery, pictured in Francesch (cover page) and in {{McKeown}}, p. 747. — Olympus Six with lens no. 7157: example observed in an online auction. </REF> The lens no. 6358 would not have been produced before about 1939.
| |
| − | | |
| − | It is thus likely that the two surviving cameras are composite. They were probably created by the company itself, outside the regular production. They could have been made to dispose of a stock of unsold Semi Olympus bodies. However the fact that one of them remains the property of the company suggests that they were made for an internal purpose, perhaps to serve as a testbed for the Koho shutters.

| − | The Semi Olympus II is a horizontal folder taking 4.5×6cm pictures. The folding struts are the same as on the [[Balda]] products, certainly under the influence of the previous Semi Olympus. The camera has a tubular viewfinder, an advance knob at the left end of the top plate and an accessory shoe at the right end. The serial number is engraved in the advance knob, together with an arrow indicating the winding direction. The back is hinged to the left and the back latch is covered by a leather handle; there are two red windows at the bottom to control the film advance, covered by a black plate pivoting on an axis in the middle. The bottom of the camera has two film flanges, with the shape of a truncated cone; one has a 1/4″ tripod thread and the other has a 3/8″ thread. The ''OLYMPUS TOKYO'' logo is embossed at two places: in the back leather (above the red windows) and in the handle. The lens is the same Zuiko 75/4.5 as on the previous Semi Olympus.
| |
| − | | |
| − | === Evolution through original documents ===
| |
| − | The Semi Olympus II was advertised in ''[[Asahi Camera]]'' from October 1937 to March 1940, and it was featured in the January 1938 issue of the same magazine.<REF> {{Kokusan}}, p. 335. </REF>
| |
| − | | |
| − | The '''first version''' of the camera is pictured in advertisements from October 1937 to February 1938 and in a brochure dated 1937.<REF> [http://www.olympus-zuiko.com/dev_spirits/maitani/pdf/semi_olympus.pdf Brochure] available in pdf format in [http://www.olympus-zuiko.com/dev_spirits/maitani/vol01/index.html this page of the Zuiko Club website]. It has a sticker indicating a price of ¥105. </REF> The viewfinder is offset to the left (as seen by the photographer) and the folding bed release in in the middle of the top plate. In the documents, the shutter is called Laurel (ローレル, ''rōreru'') and is said to give 1–150, B, T speeds with a self-timer. The name ''LAUREL'' is engraved at the base of the speed rim. The shutter plate is inscribed ''OLYMPUS-TOKYO-N'' at the top and the aperture scale is at the bottom. No surviving example has been observed with the offset finder and the Laurel shutter, and it is not clear whether this version was actually sold.
| |
| − | | |
| − | In the October 1937 advertisement in ''[[Asahi Camera]]'',<REF> Advertisement (on p. A59 of the magazine) reproduced in {{Kokusan}}, p. 62, and in Hibi, p. 62 of {{KKS}} no. 8. </REF> no price is given and the camera is presented together with the [[Olympus Standard]]; [[Misuzu Shōkai]] and [[Yamashita|Yamashita Yūjirō Shōten]] are given as authorized dealers for the Standard, and it is unclear whether this applies to the Semi II as well.
| |
| − | | |
| − | The advertisement that appears in the November and December issues of ''Asahi Camera'' photographs the camera from a slightly different angle, prices the camera at {{yen|95|1937}}, and names Misuzu and Yamashita as distributors for the Standard, not mentioning any distributor for the Semi. In the full-page advertisement for the Semi Olympus II in the January 1938 issue of ''[[Asahi Camera]]'', the Laurel shutter is stated to be designed by Takachiho based on the Prontor II shutter. Yamashita is given as the distributor. The advertisement in the February issue is revised: the distributors are now Yamashita and [[Mizuno|Mizuno Shashinki-ten]]<!-- 水野寫眞機店, of 東京都下谷区上車坂 -->.
| |
| − | | |
| − | The advertisement in the March 1938 issue of ''[[Asahi Camera]]'' is the first in that magazine to show the '''regular version''', with the tubular finder in the middle of the top plate and the folding bed release on the right. That in the April issue at first looks the same, but there is no mention of the shutter (which is anyway not shown in the photograph of the camera).
| |
| − | | |
| − | One of the pictures in the May 1938 advertisement in ''[[Asahi Camera]]''<REF> Advertisement reproduced in Hibi, p. 62 of {{KKS}} no. 8. </REF> shows a number of cameras from a distance (at least twenty), indicating that the serial production of the camera bodies had begun. In another picture showing a camera from a closer distance, the shutter rim reads ''DAURED'' (or possibly ''DAUREL''). It is not clear whether this engraving actually existed or if this is a retouched picture of a camera with Laurel shutter. It is said that the Laurel name was dropped because it was already registered by another company,<REF> Francesch, p. 24. Hibi, p. 63 of {{KKS}} no. 8, says that it was registered by [[Tōkyō Kōgaku]] but this is perhaps a confusion with the postwar [[Laurelflex]] made by that company. </REF> and the Daured name appearing in this advertisement was certainly the result of a hasty move. The shutter has speeds of 1–150, B, T, and the lens number is legible as 1448 or 1446. The lens number 144x certainly means that less than 500 examples of the Semi Olympus and Semi Olympus II were made up to May 1938. (The pictured camera was certainly finished a short time before the advertisement was published. The company would not have published pictures of the older version in the previous advertisements if the new model was ready to be photographed.)
| |
| − | | |
| − | The advertisement in the June 1938 issue of ''[[Asahi Camera]]''<REF> Advertisement (on p. A50 of the magazine) reproduced in {{Kokusan}}, p. 62, and in Hibi, p. 62 of {{KKS}} no. 8. </REF> shows the new shutter name [[Koho]] (コーホー), both in the text and on the pictured camera. The advertisement shows a mountain and a country road, with the catch-phrase "[Let's go] gallantly to the green mountains and fields" (緑の山野に颯爽と!), an allusion to the season and perhaps to the camera name Olympus and shutter name Kōhō (meaning "high peak" or "high mountain"). The company [[Honjō Shōkai]] was added to the list of authorized dealers and the price was still given as {{yen|95|1938}}.
| |
| − | | |
| − | In advertisements dated July and September 1938, February and October 1939,<REF> July 1938: advertisement published in ''[[Ars Camera]]'' reproduced in Hagiya, p. 10 of {{KKS}} no. 20. — September 1938: [http://syasinsyuu.cool.ne.jp/camera/syasinki5.jpg advertisement] published in ''[[Asahi Camera]]'' reproduced in the [http://syasinsyuu.cool.ne.jp/camera/syasinki5.jpg Gochamaze website] and in Hibi, p. 63 of {{KKS}} no. 8. — February 1939: [http://syasinsyuu.cool.ne.jp/camera/syasinki5.jpg advertisement] published in ''[[Asahi Graph]]'' (8 February 1939), reproduced in the [http://syasinsyuu.cool.ne.jp/camera/syasinki5.jpg Gochamaze website]. — October 1939: advertisement published in ''[[Asahi Camera]]'', reproduced in [http://www.warbirds.jp/heiki/31000.htm this page of the Heiki Seikatsu website]. </REF> the price was raised to {{yen|105|1938}} and the company Hinode Kōgyō K.K. (日之出興業{{kabu}}) gradually replaced the three authorized dealers and became the sole distributor. The February 1939 advertisement says that the price of ¥105 comprised a lens hood and a cable release. The top speed is given as 1/150 in all these advertisements. Incidentally, in all the advertisements for the Semi Olympus II, the lens is called 瑞光 ("Zuikō" in ''kanji'' script) while the shutter is called コーホー ("Kōhō" in ''katakana'' script).
| |
| − | | |
| − | The Semi Olympus II was advertised in ''[[Asahi Camera]]'' until the March 1940 issue.<REF> {{Kokusan}}, p. 335. </REF> It was still mentioned in the official list of set prices compiled in October 1940 and published in January 1941, for ¥121.<REF> {{Kakaku1940_short}}, type 3, section 6B. </REF> It was also in a similar price list dated November 1941, for an unknown price.<REF> {{Kakaku1141_short}}, type 3, section 6B. </REF> The Olympus Six was already available for sale at that time, the observed serial numbers seem to indicate that there was no overlap in the production of the the two models. It is thus presumed that these prices applied to the remaining stocks of the Semi Olympus II, held by the company or by the retailers.

| − | === Surviving examples ===
| |
| − | All the examples observed of the Semi Olympus II have the viewfinder centred above the top plate and a [[Koho]] shutter. The early examples have 1–150, B, T speeds. The earliest lens number observed so far is no. 2001.<REF> Example pictured in Francesch (cover page) and in {{McKeown}}, p. 747. </REF> This camera was necessarily made after the May 1938 "Daured" episode (see above): if the camera was available before, the company would not have used a picture (original or retouched) showing the name Daured in the May 1938 advertisement, and would have used a photograph of a camera with Koho shutter instead. This is a hint that very few Olympus cameras were made before that date.

| − | On all the examples observed of the Semi Olympus II, the lens engraving differs from the early engraving found on the previous Semi Olympus. It is ''Zuikô 1:4,5 f=7.5cm Takatiho Tokyo No.xxxx'' (circunflex accent) up to lens no. 3797 and ''Zuiko 1:4,5 f=7.5cm Takatiho Tokyo No.xxxx'' (no accent) from lens no. 5253.<REF> Lens no. 3797: example pictured in Francesch, p. 58, in {{Sugiyama}}, item 1215, in Hagiya, p. 14 of {{KKS}} no. 20 and in [http://www.geocities.jp/o_photoclub/OLYHistory/details/1930/1930_07.html this page of the Olympus Photo Club].

| |
| − | | |
| − | Later examples have 1–200, B, T speeds, with no other change. Lens no. 5253 is associated with 1/150 top speed and lens no. 5389 with 1/200 top speed, and the transition probably occurred around that time.<REF> Lens no. 5389: example observed in online auctions: body no. 5362, lens no. 5389; lens no. 5454. </REF> However the different parts constituting the camera (body, shutter and lens) were not used in strict sequence: for example, lens no. 5253 goes with body no. 5368 and lens no. 5389 goes with the earlier body no. 5362.

| − | == Olympus Six ==
| |
| − | Released in 1940,<REF> See the documents presented below. This date is also given in [http://www.olympus-global.com/en/corc/history/camera/index.cfm?ote=1 this page of the Olympus official website]. Some sources say that the Olympus Six was released in 1939 but this is a mistake. </REF> the '''Olympus Six''' (オリンパス・シックス) is a dual-format model and can take 6×6cm and 4.5×6cm pictures with a mask.
| |
| − | | |
| − | === Description ===
| |
| − | The Olympus Six is a horizontal folder, and its folding struts are similar to that of the Semi Olympus II. There is a folding optical finder in the middle of the top plate. Two hairlines are engraved in the front glass, indicating the field of view for 4.5×6cm exposures. The folding bed release is immediately to the left of the viewfinder, as seen by the photographer. There is a body release at the right of the top plate, next to the right-hand film flange. The advance knob is at the left end, it has the serial number and an arrow engraved, as on the Semi Olympus II. There are strap lugs at both ends of the top plate, replacing the leather handle of the previous model, and there is no accessory shoe.
| |
| − | | |
| − | The back is hinged to the right and the back latch consists of a long sliding bar. There are two red windows in the back, one for each format, with a sliding cover accordingly marked ''6X6'' or ''4.5X6''. The bottom plate has two film flanges at the ends, and a 3/8″ tripod thread in the middle.
| |
| − | | |
| − | The ''OLYMPUS TOKYO'' logo is embossed in the leather of the folding bed, and the name ''OLYMPUS–SIX'' or ''SUPER–OLYMPUS'' is embossed in the back, under the red windows.
| |
| − | | |
| − | === Early lens and shutter ===
| |
| − | The first lenses mounted on the Olympus Six are the Zuiko 75/4.5 (same as on the Semi Olympus) and the new Zuiko 75/3.5. They are engraved ''Zuiko 1:4,5 f=7.5cm Takatiho Tokyo No.xxxx'' and ''Zuiko 1:4,5 f=7.5cm Takatiho Tokyo No.xxxx''.
| |
| − | | |
| − | The shutter originally mounted on the camera is a newer version of the [[Koho]], giving 1–200, B, T speeds and adapted to the body release linkage. It still has a self-timer but does not have a thread for a distant release. Other shutters were mounted towards the end of the production, see below.
| |
| − | | |
| − | Whatever the shutter and lens model, the camera has a black depth-of-field scale around the lens, marked ''OLYMPUS'' at the bottom. The aperture scale consists of a metal plate placed above the shutter housing, and it is combined with a second scale of shutter speeds, readable from the above.
| |
| − | | |
| − | === Announced as the Semi Olympus III ===
| |
| − | The camera was first announced as the '''Semi Olympus III''' (セミオリンパスⅢ型), quite a strange name for a 6×6 camera. It was featured under that name in the July 1940 issue of ''[[Asahi Camera]]'' and was advertised as such in the June and July 1940 issues of the same magazine.<REF> {{Kokusan}}, p. 335. </REF> In the June advertisement,<REF> Advertisement reproduced in {{Kokusan}}, p. 62, and in Hibi, p. 63 of {{KKS}} no. 8. </REF> the camera is announced as a new model (愈々新型発売) in dual format (6×6 and 4.5×6), and the body release and depth-of-field scale are emphasized. The shutter is mentioned as a Koho II (コーホーⅡ), giving 1–200, B, T speeds, with a self-timer. Two versions are presented, one has a Zuiko (ズイコー) 7.5cm f/4.5 lens and is priced at {{yen|190|1940}}, the other has a Zuiko 7.5cm f/3.5 lens and is priced at {{yen|235|1940}}. A lens hood is also listed for ¥3. The company names given in the advertisement are the maker [[Olympus|Takachiho Seisakusho]] and the distributor [[Ataka|Ataka Shōkai]]. The pictured camera is indistinguishable from the Olympus Six with f/3.5 lens, there was probably no difference other than the name embossing in the back. No surviving example has been observed so far with markings other than ''OLYMPUS–SIX'' or ''SUPER–OLYMPUS'', and the name Semi Olympus III was probably dropped before the camera entered serial production.
| |
| − | | |
| − | === The Olympus Six in wartime documents ===
| |
| − | The Olympus Six was first advertised under that name in the December 1940 issue of ''[[Asahi Camera]]'', and it was featured in the April 1941 issue of the same magazine.<REF> {{Kokusan}}, p. 335. </REF> The advertisements dated December 1940 and April 1941 in ''[[Asahi Camera]]''<REF> Advertisements reproduced in Hibi, p. 63 of {{KKS}} no. 8. The December 1940 advertisement is also reproduced in {{Kokusan}}, p. 63. See also [http://www.remus.dti.ne.jp/~inasan99/camera/b_camera/rollcko_l.jpg this advertisement] dated 1942 or later, reproduced in [http://www.remus.dti.ne.jp/~inasan99/camera/nostalgic_camera.html Nostalgic Camera] by Toshio Inamura. </REF> mention the f/3.5 and f/4.5 lens options, and say that the lenses have four elements. The shutter is called New Koho III (新コーホーⅢ) but has the same features (1–200, B, T, self-timer) as the shutter called Koho II in the advertisement for the Semi Olympus III. The distributor is still [[Ataka|Ataka Shōkai]].
| |
| − | | |
| − | The December 1940 advertisement only mentions 6×6cm format only (more precisely "6×6m/m", with a typo), whereas the April 1941 advertisement again mentions the dual-format capability. This has been interpreted by some sources as an indication that the Olympus Six was sold for some time in a single-format version,<REF> Hibi, p. 64 of {{KKS}} no. 8. See also [http://www.geocities.jp/o_photoclub/OLYHistory/details/1940/1940_03.html this page] and [http://www.geocities.jp/o_photoclub/OLYHistory/details/1940/1940_04.html this page] of the Olympus Photo Club website, certainly after Hibi. </REF> but this probably only reflects a negligence in the advertisement. All the cameras observed so far have two red windows in the back and are dual format.
| |
| − | | |
| − | The picture is the same in the two advertisements, and shows an Olympus Six with f/4.5 lens, recognized by the double lens rim already present on the Semi Olympus II. One source says that the the lens bezel and lens rim differ between the Semi Olympus III and the Olympus Six,<REF> {{Kokusan}}, p. 335. </REF> but this apparent difference is only caused by the various lens types (f/3.5 and f/4.5) pictured in the advertisements.
| |
| − | | |
| − | In a brochure for the Olympus Six,<REF> [http://www.olympus-zuiko.com/dev_spirits/maitani/pdf/olympus_six.pdf Brochure for the Olympus Six] available in pdf format in [http://www.olympus-zuiko.com/dev_spirits/maitani/vol01/index.html this page of the Zuiko Club website]. </REF> the shutter is called Koho III. Model names and officially set prices are given for The two versions are listed, with their exact model name and the officially set price: the '''Olympus Six I''' (オリンパス・シックスⅠ) with the f/4.5 lens, for ¥128, and the '''Olympus Six II''' (オリンパス・シックスⅡ), with the f/3.5 lens, for ¥160. A lens hood is mentioned, fitting both the f/4.5 and f/3.5 lens, and a filter holder (フィルター枠), to fit 30mm diameter filters on the f/4.5 lens.
| |
| − | | |
| − | The Olympus Six I and II were mentioned in the official list of set prices published in January 1941 and already cited above.<REF> {{Kakaku1940_short}}, type 4, sections 5B and 6B. </REF> The prices were the same as in the brochure cited above, which is thus probably dated late 1940 or early 1941.
| |
| − | | |
| − | The Olympus Six was advertised in ''[[Asahi Camera]]'' until the last wartime issue dated April 1942, and it was advertised in ''[[Hōdō Shashin]]'' from December 1941 to May 1943.<REF> {{Kokusan}}, p. 335. </REF> The shutter is reportedly called Koho II in the advertisements published in ''Hōdō Shashin''.<REF> {{Kokusan}}, p. 335. </REF> Some confusion seemed to reign about the exact model name of this shutter at the time.
| |
| − | | |
| − | === Early surviving examples ===
| |
| − | The oldest lens numbers observed on the Olympus Six are on the cameras pictured in the brochure cited above: no. 697x for the f/4.5 lens and no. 7242 for the f/3.5 lens, both mounted on a [[Koho]] shutter to 1/200. (However, the f/3.5 lens no. 7182 is known with a Koho shutter on what is said to be a prototype of the Olympus Chrome Six, see [[#Olympus Chrome Six I/II/III|below]].)
| |
| − | | |
| − | Some early examples have a specific aperture index with two ears, whereas others have a simple pin. The two-ear index appears in the brochure and in all the advertisements, and it has been observed on actual examples with f/4.5 lens no. 7157 and f/3.5 lens no. 7382 and 10626.<REF> Lens no. 7157 and lens no. 7382: examples observed in online auctions.

| − | === Production resumed after the war ===
| |
| − | The production of the camera was resumed in early 1946, and the production details are given month by month in Lewis: 77 cameras in January 1946, 89 in February, 202 in March, 198 in April, 160 in May, 250 in June and 129 in July.<REF> Lewis, p. 60. </REF> The supply of shutters was certainly the main problem encountered by Takachiho. (Its own shutter plant was destroyed by aerial bombing in spring 1945.)<REF> Francesch, p. 28. </REF> This may have led the company to use any shutter it could find, hence the variety of shutters found on the surviving Olympus Six bodies described below. It is said that [[Mamiya]] sold some Koho shutters back to [[Olympus|Takachiho]], from a lot bought during the war for the [[Mamiya Six]], exchanging them for new Zuiko lenses.<REF> Lewis, p. 64. Same information in Sakai, p. 7 of {{KKS}} no. 20, not explicitly mentioning Mamiya. </REF>
| |
| − | | |
| − | The Olympus Six was advertised in ''[[Ars Camera]]'' from January to March 1948. The January advertisement<REF> Advertisement reproduced in {{Kokusan}}, p. 125, and in Hibi, p. 64 of {{KKS}} no. 8. </REF> mentions a Zuiko f/3.5 lens and a Koho shutter (1–200, B, T). The pictured camera has a Koho shutter and a two-ear aperture index, as in the wartime advertisements.
| |
| − | | |
| − | === Late observed examples ===
| |
| − | Immediately after the Zuiko-S lenses no. 12126, 125xx and 13501, the earliest lens numbers observed on an Olympus Six are no.20016, 20224, 20309 and 20727 (all with Koho shutter), mounted on bodies in the 12xxx and 13xxx range.<REF> Lens no.20016, body no.12936: example observed in an online auction. Lens no.20224: example pictured in Fujishima, p.22 of {{KKS}} no.8. Lens no.20309: example pictured in a website which is currently dead. Lens no.20727, body no.13501: example observed for sale by a French dealer at the Bièvres fair (2006 and 2007). </REF> The earliest two have the ''SUPER–OLYMPUS'' embossing on the back, the third has ''OLYMPUS–SIX'', as well as all subsequent cameras.
| |
| − | | |
| − | The gap between lens no. 13501 and 20016, as well as the sudden offset between the body number and lens number, perhaps indicates that the serial number sequence was reset at 20000. If the story about the Zuiko-S being made because of the shortage of imported optical glass is true, the production of the regular Zuiko lens was logically not resumed before 1945. This would mean that any lens number after 20000 is an indication of a postwar camera. The first postwar lenses were certainly mounted on bodies available in the stocks, including some that were already finished except for the lens and shutter assembly, hence the markings identifying the earliest ones as Super Olympus.
| |
| − | | |
| − | Other postwar examples with the Koho shutter have lens no. 22610 (body no. 13610), lens no. 23504 (body no. 14210) and lens no. 25625 (body no. 15013).<REF> Examples observed in online auctions. </REF>
| |
| − | | |
| − | An Olympus Six has been observed with a no-name shutter giving T, B, 1–250 speeds, and lens no. 24961.<ref> Example observed in [http://www.gold-camera.com/photo/pic.asp?iCat=59&iPic=1355 this page of a Chinese website]. </ref> Three examples of the Olympus Six have been observed with a different no-name shutter giving 1–300, B, T speeds, and lens no. 24964, 25718 and 25754.<REF> Lens no. 24964 and 25718: examples observed in online auctions. Lens no. 25754: example pictured in {{Sugiyama}}, item 1216. Some sources say that this is a version of the Olympus Six sold in 1940 but this is certainly a mistake. </REF>
| |
| − | | |
| − | The very late examples of the Olympus Six (with lens number above 30000) have no strap lugs. Four examples have been observed, each having a different shutter type. One example has lens no. 30387 and an unmarked shutter giving 1–200, B, T speeds.<REF> Example pictured in {{Sugiyama}}, item 1370. </REF> (This shutter is not a Koho: the cocking lever is placed differently.) The most well-known example, belonging to the [[Olympus]] company, has lens no. 30780 and a [[Copal]] shutter giving 1–200, B, T speeds, the same as on the later Olympus Chrome Six.<REF> Example pictured in Francesch, p. 61, in {{McKeown}}, p. 748, in {{Sugiyama}}, item 1371, in Hagiya, p. 15 of {{KKS}} no. 20, in [http://www.geocities.jp/o_photoclub/OLYHistory/details/1940/1940_04.html this page] and [http://www.geocities.jp/o_photoclub/OLYHistory/details/1940/1940_16.html this page] of the Olympus Photo Club website. </REF> The third example is the latest known with a [[Koho]] shutter: it has lens no. 31665 and body no. 17328.<REF> Example observed in an online auction. </REF> The last example has a Wester shutter giving 1–200, B, T speeds, made by [[Nishida]] and engraved ''WESTER. <small>N.S.D.</small>'' at the base of the speed rim.<REF> Example observed in an online auction. </REF> The lens number is 32707 and the body number is 18020; these are the latest numbers observed on an Olympus Six, and the lens number is even slightly later than no. 32603, known on an example of the Olympus Chrome Six.<REF> Example pictured in Francesch, p. 62 and in {{McKeown}}, p. 748, in [http://www.olympus-global.com/en/corc/history/camera/index.cfm?ote=1 this page of the Olympus official website] and in [http://www.geocities.jp/o_photoclub/OLYHistory/details/1940/1940_12.html this page of the Olympus Photo Club website]. </REF>
| |
| − | | |
| − | The offset between the lens and body numbers has widened, certainly because Zuiko lenses were sold to other companies, such as [[Mamiya]] for the [[Mamiya Six]]. Admitting that the postwar examples have lens numbers above 20000 and body numbers after about 13000, this would make a total of about 5,000 Olympus Six cameras and 12,000 Zuiko lenses made between early 1946 and the release of the Olympus Chrome Six in 1948. This is quite consistent with the total of 1,015 cameras for the period between January and July 1946.
| |
| − | | |
| − | === Production estimate ===
| |
| − | From the above data, a rough estimate gives more than 6,000 prewar and wartime Olympus Six, with close lens and body numbers, comprised between c.7000 and c.13500, and about 5,000 postwar cameras, with body numbers between c.13000 and c.18000 and lens numbers between 20000 and c.33000.
| |
| − | | |
| − | === Hybrid advertisements ===
| |
| − | The last advertisements for the Olympus Six are in the May to July 1948 issues of ''[[Ars Camera]]''.<REF> {{Kokusan}}, p. 348. </REF> The text of the May advertisement<REF> Advertisement reproduced in {{Kokusan}}, p. 125. </REF> is similar to the one dated January: the camera is called Olympus Six, the lens is the Zuiko f/3.5 and the shutter is the Koho (1–200, B, T). However at first glance, the picture shows a hybrid between the Olympus Six and the Olympus Chrome Six. Upon closer inspection, only the bottom part of the illustration is an original picture, showing an Olympus Six, whereas the top part is a drawing of the top plate of the future Olympus Chrome Six.

| |
| − | | |
| − | In 1948 the '''Olympus Chrome Six I''' introduced a diecast body, a chrome top plate, an accessory shoe and a rigid optical finder. It had a [[Zuiko]] 7.5cm f:3.5 lens and a [[Copal]] 1–200, B, T shutter. It still had the ability to take pictures in 4.5×6 format with a mask. Inside the finder a blue filter distinguished the 4.5×6 picture frame. There was also a vertical parallax index. The body was only marked ''Olympus Six'' on the top plate, with ''Olympus-Six'' embossed in the back. All the following models shared these markings, which today often cause confusion.
| |
| − | | |
| − | The '''Chrome Six II''', also released in 1948, was the same camera with a Zuiko 7.5cm f:2.8 lens.<ref>The chronology at the Olympus corporate site says it was equipped with the film surface stabilizer, which is certainly a confusion with the next Chrome Six III model.</ref>
| |
| − | | |
| − | The Chrome Six I and II progressively evolved during their production run. The very first examples had a low accessory shoe made of sheet metal, soon changed for a higher diecast part (usually said to be the distinguishing feature of the Chrome Six III, but see below). At about the same time, the shutter's distant release connector disappeared and the lens became coated. A little after, the aperture command was changed from a small index to a longer one.
| |
| − | | |
| − | The shutter was later changed from the unsynchronized Copal 1–200, B, T to the synchronized Copal B, 1–200, marked ''S.COPAL'' on top, called Synchro-Copal in the manuals. The sync connector was of the ASA bayonet type. Three examples have been observed of a synchronized Copal 1–200, B, T shutter, not marked ''S.COPAL''. The three of them were different. One had a PC type connector on the left, another had an ASA bayonet connector on the top left and the third one had an ASA connector on the top right like the later Synchro-Copal. It is not known if these were original fittings.
| |
| − | | |
| − | At some time the advance knob slightly evolved too, from a model with flat top and an arrow engraved (in two successive shapes) to a model with no arrow and a somewhat recessed top.

| − | During this period, the lens markings evolved too, from ''Takatiho Tokyo Zuiko'' on the early lenses to ''Olympus Zuiko F.C.'' on the late lenses. The transition from Takatiho to Olympus probably occurred in 1949 with the company's name change. It apparently occurred together with the adoption of lens coating. Here are the observed lens markings for the f:3.5 lens, ordered by ascending lens number:
| |
| − | * ''Takatiho Tokyo Zuiko 1:3.5 f=7.5cm''
| |
| − | * ''Olympus Zuiko Coated 1:3.5 f=7.5cm''
| |
| − | * ''Olympus Zuiko C. 1:3.5 f=7.5cm'' with red ''C.''<ref>See [http://homepage.mac.com/cameradecollection/folding/Pages/51.html here].</ref>
| |
| − | * ''Olympus Zuiko C. 1:3.5 f=7.5cm'' with black ''C.''<ref>See [http://www.triplethouse.com/PREV/OlympusSix%20PREV/Olympus.html here].</ref>
| |
| − | * ''Olympus Zuiko F.C. 1:3.5 f=7.5cm''
| |
| − | Similar markings have been observed for the f:2.8 lens, all written in white on a black lens bezel.
| |
| − | | |
| − | It is usually said that the changes distinguishing the next '''Chrome Six III''' model from the previous Chrome Six I and II were the bigger diecast accessory shoe, the synchronized shutter with B, 1–200 speeds and the film reminder. However an English user manual for the Olympus Chrome Six<ref>Observed in an online auction, with "Nov 13, 1951" handwritten on it.</ref> presents a model with big accessory shoe, Synchro-Copal shutter and coated lens but no film reminder, and calls it "Model I coated Zuiko 1:3.5 f=7.5cm" and "Model II coated Zuiko 1:2.8 f=7.5cm". In contrast the user manual of the Chrome Six III<ref>Available [http://www.butkus.org/chinon/olympus_chrome_six/olympus_chrome_six.htm here] at butkus.org.</ref> presents a camera with a film reminder and a device called "film plane corrector"<!-- I think I can explain it, at least a little. Please wait a day or so. -->, located underneath the film reminder according to one of the pictures. The purpose of this device was apparently to tension the film to enhance the film flatness. The manual of the Chrome Six III emphasizes the film plane corrector as the main innovation of the new model. It is probable but not certain that the cameras without film reminder did not have the film plane corrector either, and were sold as Chrome Six I or II. The external distinguishing features of the Chrome Six III would be the film reminder and a slightly higher release button.

| − | The Chrome Six III exists in two variants, the '''Chrome Six III A''' with the Olympus Zuiko F.C. f:3.5 lens and the '''Chrome Six III B''' with the Olympus Zuiko F.C. f:2.8 lens. Both lenses are called "Zuiko Full Coated" in the manual. The Chrome Six III appeared in 1951 or 1952.<ref>A guarantee card dated Aug 20th, 1952 has been observed with a Chrome Six IIIA at an eBay auction.</ref>

| |
| − | At some point during the production of the Chrome Six III, the f:3.5 lens became an Olympus D.Zuiko F.C. It was a recomputed lens design, with new lens glass.<ref>As indicated in a brochure for the Chrome Six RII available at the Olympus corporate site.</ref> The new name indicated that the lens had four elements, D being the fourth letter in the alphabet. This lens was apparently numbered in its own sequence, with numbers starting from 100000. All the later Chrome Six models with f:3.5 lens had the same D.Zuiko F.C.
| |
| − | | |
| − | == Olympus Chrome Six IV or RI ==
| |
| − | The '''Chrome Six IV A''' and '''Chrome Six IV B''' from 1954 had an uncoupled rangefinder added under a top housing, and combined with the viewfinder. You had to find the distance with a knob at the back left, then adjust the front lens ring accordingly. The film reminder was the same as for the Chrome Six III, but the release button was shorter. The IV A variant had the D.Zuiko F.C. f:3.5 lens and the IV B had the Zuiko F.C. f:2.8 lens. It is said that the IV A model was sometimes called '''Chrome Six RI A'''. Probably the IV B was also called '''Chrome Six RI B'''. "RI" presumably means "Rangefinder model I". The chronology at the Olympus corporate site presents the IV A and the RI A as separate models, both from 1954, but it is not very reliable.
| |
| − | | |
| − | == Olympus Chrome Six V ==
| |
| − | The '''Chrome Six V A''' and '''Chrome Six V B''' from 1955 had a new body integrating a sleekly designed top housing. It is said that they were the first Olympus cameras designed by a specialized design staff. The top housing contained the optical finder, a recessed accessory shoe and a pyramidal release button. The opening button was now on the top of the front door. The advance knob was replaced by an advance lever at the back left. It needed six strokes to advance one exposure. On the back there was also a lever to switch a reducing mask built in the finder for the 4.5×6 format. The back door was no more embossed ''OLYMPUS-SIX'', there was an Olympus logo instead.
| |
| − | | |
| − | The V A had the D.Zuiko F.C. f:3.5 lens and the V B had the Zuiko F.C. f:2.8 lens. The shutter housing differed somewhat from the earlier versions: the depth of field scale and the aperture scale were chromed instead of black, the sync post was now of the standard PC type and there was a distant release connection. A V B has been observed with 1/300 top speed.

| |
| − | | |
| − | The '''Chrome Six RII''' had an uncoupled rangefinder and was also released in 1955. "RII" presumably means "Rangefinder model II". It was sold as '''Chrome Six RII A''' with the D.Zuiko F.C. f:3.5 lens and '''Chrome Six RII B''' with the Zuiko F.C. f:2.8 lens.
| |
| − | | |
| − | Both models existed in '''two variants'''. One of the variants had the same body and shutter housing as the Chrome Six V. The other variant inherited the body and shutter housing of the previous Chrome Six models I to IV, with a top housing styled like the Chrome Six V, including the lever advance mechanism. The opening button was on the top plate and the release button was of the old traditional style. John Foster suggests that Olympus made this variant to dispose of the remaining stock parts. Three hybrid examples have been observed combining the old body with the new folding bed (integrating the opening button) and the new shutter housing. Two of these hybrids have the usual 1/200 top speed<ref>See [http://www7a.biglobe.ne.jp/~zeppan_tousan/col4/col4.cgi?mode=main&no=100 here] and the pictures displayed above.</ref> and the other has a 1/300 top speed.<ref>See [http://mpm.kitamura.co.jp/mssm/blogs/440/4973/2006/05/_36120.html here].</ref> Francesch says that the top speed upgrade to 1/300 took place in 1956.
| |
| − | | |
| − | A brochure for the Chrome Six RII is available at the Olympus corporate site (see the links below). The cameras pictured are of the old variant. The brochure describes a device meant to correct the focus setting according to the aperture. It says that the focus distance varies in the lenses with the Tessar formula, and that Olympus was the first camera maker to take it into account. Apparently this device was simply a line traced under each distance number, indicating the focus correction for f:8 and f:5.6 apertures.
| |
| − | | |
| − | The V and RII were the last Olympus folders. In 1957 Olympus had abandoned <!-- In '57 it abandoned? By '57 it had abandoned? (I don't have the book with me, sorry.) --> the 6×6 folders and the 6×6 TLRs and were making 35mm models only.
