The Secrette (セクレット) is a Japanese plate camera, distributed from 1923 by Sone Shunsuidō, and made by its manufacturing branch Tokyo Camera Works.
The Secrette is a detective camera shaped as a monocular and taking pictures from the side, inspired by the Ergo of Contessa-Nettel. The mirror viewfinder is disguised inside the fake eyepiece. The plate holders are attached to the flat side of the camera; the distance is set by inserting the holder in one of three positions, for far, mid-range and close pictures. The shutter is a rotating drum, also acting as a lens cover when in closed position; it has T, 1/25, 1/50 and 1/75 settings.
The Secrette exists in two versions. The Regular model has a simple meniscus lens and plain leather covering. It has the words ANACHROMATIC 50m/m inscribed around the lens and TOKYO CAMERA WORKS SECRETTE around the eyepiece. The Special model has a Testar 50/4.5 lens and lizard covering. The Testar lens was specially made by a French company in Paris for Sone Shunsuidō. The lens rim reads T.C.W. PARIS TESTAR and there is a serial number. The Special also has an additional lever at the top, whose purpose is unknown.
Advertisements in Ars Camera dated April and May 1924 boast the Testar Anastigmat f/4.5 lens and lizard covering and say that the camera was delivered with six single-sided metal plate holders; they do not mention the Regular model. The April advertisement mentions No.0 size and gives no price. The May advertisement mentions atom size and gives the price of ¥85. It shows the same illustrations as the previous month and also presents the camera as the "New Argus" (新アーガス); the name New Argus was also used by Saneidō for another detective camera patterned after the original Argus or Ergo.
Surviving examples Edit
Various surviving examples are known, but mistakes are sometimes made in reporting the exposure format.
One example of the Special model, belonging to Mr Morihara, is pictured in Sugiyama and perhaps in other sources as well; it is sometimes reported as atom size and sometimes as No.0 size. The example pictured in Morishita is maybe the same, and reportedly has atom size. The JCII museum reportedly owns one example of the Special in No.0 size and one in atom size.
One example of the Regular model, belonging to Mr Kikuoka, reportedly has No.0 size. The example pictured in Morishita is maybe the same, and reportedly has No.0 size. Another example belongs to the Pentax Gallery and reportedly has atom size.
Conflicting interpretations Edit
From the documents observed so far, it seems quite clear that the Special model was first released in No.0 size, and switched to atom size at some time. No definitive conclusion can be drawn for the Regular model. It certainly exists in No.0 size; it might have switched to atom size some time after the Special model, but this is not confirmed by any advertisement, and the reports of an atom size Regular model might be mistaken. (No.0 size usually corresponds to inexpensive cameras, such as the Adam or Sweet, whereas atom size is used on more serious cameras.)
