The Semi Olympus II (セミ・オリンパス・Ⅱ型) is a 4.5×6cm folder, made from 1937 by Takachiho (later Olympus). It was the first camera entirely made by the company, after the Semi Olympus whose body was bought elsewhere. It was succeeded in 1940 by the Olympus Six, which was first announced as the Semi Olympus III, despite its different 6×6cm format.

The Semi Olympus II is a horizontal folder taking 4.5×6cm pictures. The body was designed by Mr Kitagawa (北川). The folding struts are the same as on the Balda products, certainly under the influence of the previous Semi Olympus. The camera normally has a tubular viewfinder. The advance knob is at the left end of the top plate, as seen by the photographer, and there is 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 three places: on the front door, in the back 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 Edit
First version, offset finder Edit
The first version of the camera is pictured in advertisements from October 1937 to February 1938 and in a brochure dated 1937. The viewfinder is offset to the left (as seen by the photographer) and the folding bed release is 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, reproduced below, no price is given and the camera is presented together with the Olympus Standard; Misuzu Shōkai and 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 picture shows the lens marking Takatiho Tôkyô Zuikô 1:4,5 f=75mm No.xxxx, typical of the very first lenses made by the company, as found on the Semi Olympus (I) with serial numbers in the 10xx or 11xx range.
The advertisement that appears in the November and December issues of the same magazine shows a photograph of the camera taken from a slightly different angle, with a similar lens marking. In the document, the camera is priced at ¥95, and Misuzu and Yamashita are named as distributors for the Standard, but no distributor is mentioned for the Semi II.

In the full-page advertisement for the Semi Olympus II placed in the January 1938 issue, the Laurel shutter is stated to be designed by Takachiho based on the Prontor II shutter, and Yamashita is given as the distributor. The photograph shows a different example of the Semi Olympus II, with lens marking Zuikô 1:4,5 f=75mm Takatiho Tokyo No.xxxx. This marking, with focal length in millimetres, is intermediate between that found on the Semi Olympus (I) and that found on regular examples of the Semi Olympus II.
The advertisement in the February issue is revised: the distributors are now Yamashita and Mizuno Shashinki-ten. The picture is taken from a similar angle but is not identical; it shows a camera with similar features.

The camera was announced in the new products column of the January issue, reproduced below. The document mentions the offset viewfinder and the accessory shoe for a rangefinder or a flashgun. It says that the Laurel shutter is everset, but this is clearly a mistake.

Regular version, centred finder Edit

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). The two documents show the same picture; the camera's body number is barely legible as 1072.
|March 1938||April 1938||May 1938|
|Advertisements for the Semi Olympus II in Asahi Camera. (Image rights)|
One of the pictures in the May 1938 advertisement in Asahi Camera 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). This marking probably results from a retouch applied on the photograph, and it seems unlikely that any actual camera was engraved as such. It is said that the Laurel name was dropped because it was already registered by another company, and the "Daured" retouch was certainly the result of a hasty move. On the same camera, the shutter has speeds of 1–150, B, T, and the lens number is legible as 1448 (or maybe 1446). The lens number indicates that less than 500 examples of the Semi Olympus and Semi Olympus II were made up to Spring 1938. It seems that the lens marking is now Zuikô 1:4,5 f=7.5cm Takatiho Tokyo, with focal length in centimetres.

Apparition of the Koho shutter Edit

The picture shows the centred finder, Koho shutter to 1/150, and Zuikô f/4.5 lens no.1982. (Image rights)
The advertisement in the June 1938 issue of Asahi Camera shows the new shutter name Koho (コーホー), both in the text and on the photograph. The pictured camera has a focal length in centimetres, as all later Semi Olympus II. 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 has been added to the list of authorized dealers and the price is still given as ¥95.
|June 1938||September 1938||January 1939|
|Advertisements in Asahi Camera. (Image rights)|
In advertisements dated July and September 1938, January, February and October 1939, the price has raised to ¥105 and the company Hinode Kōgyō is gradually replacing the three authorized dealers to become the sole distributor. The top speed is given as 1/150 in all these advertisements. The September 1938 advertisement in Asahi Camera makes it clear that "the Semi Olympus [II] is a camera by Takachiho, that was produced with the purpose of popularizing the Zuikō [lens]". Incidentally, in all the advertisements for the Semi Olympus II, the lens is called 瑞光 ("Zuikō") in kanji script whereas the shutter is called コーホー ("Kōhō") in katakana script.
The same features and price appear in the leaflet reproduced on the right, published by the retailer Photo News Sha in November 1938, and in two undated brochures reproduced in the official Olympus history website. These documents specify that the price of ¥105 comprised a lens hood and a cable release.
Serial numbers are sometimes legible in the documents. The picture used in most magazine advertisements from July 1938 onwards shows lens no.1622 (legible in the September 1938 issue of Asahi Camera). One of the brochures shows a different camera with lens no.1675 or 1678. The two cameras used for these photographs were among the first with a Koho shutter, and were made no earlier than Spring 1938. Finally, the leaflet by Photo News, printed a few months later, shows lens no.1982.
Advertisements for the Semi Olympus II were placed in Asahi Camera until the March 1940 issue. The camera still appears in the official list of set prices compiled in October 1940 and published in January 1941, at ¥121. It is also mentioned in a similar price list dated November 1941, for an unknown price. The Olympus Six was already available for sale at that time, and the observed serial numbers seem to indicate that there was no overlap in the production of the two models. It is thus presumed that these set prices applied to the remaining stocks of the Semi Olympus II, held by the company or by the retailers.
Surviving examples Edit
With Laurel shutter Edit
A single surviving camera is known with a Laurel shutter; it has body no.1063, and lens no.1221, and was pictured in an issue of Camera Collectors' News. It is very likely that the sequence of body serial numbers started at 1001, a common practice among Japanese manufacturers of the time, whereas the sequence of lens numbers continues that of the Zuiko lens mounted on the Semi Olympus. Body no.1063 is slightly earlier than no.1072 with centred tubular finder visible in the March and April 1938 advertisements in Asahi Camera.
The camera differs from the models described above by its folding optical finder, centred on the top plate. It was examined by Awano Mikio, editor-in-chief of Camera Collectors' News, who said that the finder looked genuine, but the possibility that it was exchanged at some time cannot be discarded. The folding bed release is at the same position as on regular cameras with centred tubular finder.
The Laurel shutter gives 1–150, B, T speeds, and looks the same as the Koho, but for the name LAUREL engraved on the speed rim. The lens bezel reads Zuikô 1:4,5 f=75mm Takatiho Tokyo No.xxxx with focal length in millimetres, as in the advertisements dated early 1938.
The comparison of body and lens numbers might hint that about 160 Zuiko lenses were made for the Semi Olympus before the company switched to the model II. However this subtraction should be handled with care, because the lenses were not fitted to the camera bodies in strictly ascending order.
With DAURED shutter
In early 2020 a Semi 2 camera with a DAURED shutter was purchased by an English collector/historian. The camera originated in Japan. It is the 'standardised' Semi 2 layout with a central tube finder and folding bed release to the left when viewed from the front. Body number is 1249 fitted with lens number 1690. Detailed inspection shows the shutter to be a LAUREL shutter that has been partially re-engraved converting both letter 'L' to letter 'D'. This appears to have been achieved by engraving an inverted letter 'L' very carefully positioned immediately alongside the 'Ls' of LAUREL. The style/font of the original engraving is similar to today's Arial, but although rounded letters are used in the 'U' and the 'R' of the original LAUREL, the newly formed 'Ds' are square-edged. The re-engraving has obviously been done to a dismantled shutter ring, by machine, on a jig and most likely in the Olympus factory/workshop.
The DAURED shutter gives 1-150, B, T speeds and is identical to the Laurel and Koho shutters except for the name. The lens bezel reads Zuikô 1:4,5 f=7.5cm Takatiho Tokyo No.1690 with focal length in centimetres.
The history of the camera is unknown. Its general condition is very good and it appears not to have been abused or modified in any way. Questions arise: was this camera ever commercially sold; is it purely a mock-up for the illustrators preparing adverts for publishing immediately after the LAUREL shutter copyright issue but before the KOHO shutter was available; it is late in the sequence of Laurel shuttered cameras appearing in early adverts so could it be part of a small number of Laurel shutters re-engraved to Daured by Olympus in response to copyright problems and to use their final stock before fitting the later KOHO shutter?
The cosmetic condition for a camera of this age (82 or 83 years) as well as the fact that shutter and delayed action run almost perfectly might suggest it has spent a great deal of its life in its fitted Olympus Tokyo leather case. Whether this was in a forgotten back-office within the Olympus factory or its Research Institute at headquarters or in on a private collectors shelf is unknown. But its discovery demonstrates that whatever conclusions historians may reach are almost certain to be contradicted at some future point by an example that perhaps should not exist.
The last image is a close-up of the DAURED engraving. It is clearly a re-engraved Laurel shutter.

With Koho shutter Edit

All the other examples of the Semi Olympus II observed so far have the viewfinder centred above the top plate and a Koho shutter. The early examples have 1–150, B, T speeds. The lowest numbers reported so far on a surviving example with Koho shutter are body no.1315 and lens no.1790.
| Koho shutter to 1/200, no T setting.|
An example is known with a folding optical finder centred above the top plate, instead of the tubular finder. The part is different from that found on the camera with Laurel shutter, and is probably not original.
On all the Semi Olympus II observed with Koho shutter, the lens engraving has a focal length in centimetres. It reads Zuikô 1:4,5 f=7.5cm Takatiho Tokyo No.xxxx (with circunflex accent) up to lens no.3797 and Zuiko 1:4,5 f=7.5cm Takatiho Tokyo No.xxxx (with no accent) from lens no.5253.
|Semi Olympus II no.5696, Zuiko 7.5cm f/4.5 lens no.5x94, Koho shutter to 1/200.|

Later examples have 1–200, B, T speeds, with no other change. The last known example with 1/150 top speed has body no.5368 and lens no.5253, and the earliest known example with 1/200 has body no.5362 and lens no.5389. The different parts constituting the camera (body, shutter and lens) were not used in strict sequence, explaining the small overlap in the body numbers.
One isolated example, pictured in this page, is known with 1–200, B speeds and no T setting. It has body no.6641 and lens no.6168 — the body number is the highest observed so far on a Semi Olympus II.

Finally, a camera has been exhibited by the Korean branch of the Olympus company in 2008 and 2009. It has lens no.6257, the highest known on a Semi Olympus II, and a Koho shutter to 1/200 with T setting. Its viewfinder is not original, and was taken from an Olympus Chrome Six.
