The Doris (ドリス) is a Japanese 4.5×6 folding camera made between 1952 and 1955 by Tōkyō Seiki, later Doris Camera.[1] This company was the successor of the prewar Motodori and Nissan Kōgaku, presumably founded by a Mr Motodori (本鳥). It is said that this is the source of the camera's name: "Dori's camera", thus "Doris".[2]

The Semi Rocket, a possible predecessor Edit

Tōkyō Seiki announced a 4.5×6 folder called Semi Rocket (セミロケット) in 1951 and 1952. It is said that it had an uncoupled rangefinder, a Perfa f/3.5 lens and a Convex-Rapid shutter, synchronized and giving B, 1–500 speeds. The only mention of this model has been found in Kokusan kamera no rekishi, and no picture has been observed. It seems that the Semi Rocket was only announced in some Japanese camera magazines and never advertised, and it was probably never sold. The exact relationship with the Doris is unknown.[3]

General description Edit

The Doris is a vertical folder, with folding struts inspired from the Ikonta. The viewfinder is contained in a top housing, that supports the advance knob and the body release on the left side, and the accessory shoe and folding bed release to the right above the viewfinder. The back is hinged to the left and has a single red window near the top, protected by a horizontally sliding cover. The front leather and the folding struts are marked DORIS in curved letters.

The Doris Edit

The original model has a depth-of-field dial on the right end of the top plate, and the viewfinder window is surrounded by a metal frame screwed to the top housing. The front of the top housing has two black lines mimicking the ones that appear on the Pearl, except that they are on the other side of the finder. The name DORIS is engraved above the viewfinder in the same curved font as the front leather and folding struts. The serial number is also engraved above the top housing.

The Doris was offered as a new product in an advertisement in Asahi Camera July 1952.[4] The lens is a coated Perfa Anastigmat 75/3.5 and the shutter is a NKS giving B, 1–200 speeds, with a self-timer and an ASA bayonet synch post.

This variant has not yet been observed. It was replaced by the Doris-P at the end of 1952.[5]

The Doris-P Edit

The Doris-P[6] is a cheaper model. Its appearance is similar except that the depth-of-field dial is replaced by a smaller decorative knob.

The Doris-P was offered as a new product for ¥7,000 in an advertisement in Asahi Camera November 1952.[7] The shutter is still a NKS but it gives B, 10–200 speeds. Other features are unchanged.

The Doris-P has been observed with various shutter types. All have a self-timer and an ASA bayonet synch:

  • NKS, B, 10–200;[8]
  • Convex, B, 10–200 (the speed rim is engraved CONVEX);[9]
  • MSK, B, 1–200 (the speed rim is engraved MSK and there is an OKK logo).[10]

The Doris-P was advertised until 1954.[11]

The Doris IA Edit

The Doris IA is an evolution of the Doris-P. There is no metal frame surrounding the viewfinder window, the small decorative knob on the right is replaced by a larger one and the advance knob is replaced by a newer one, with a striated rim and a red arrow engraved on the top. The DORIS engraving above the top housing has a more squarish lettering while the other DORIS markings are unchanged. It seems that some examples have two black lines on both sides of the viewfinder window while other ones only have them on one side like the previous models.[12]

The lens is a front-cell focusing Doris C. 75mm f/3.5 and the shutter is a Helio giving B, 10–200 speeds, equipped with a self-timer and synchronized via a PC post. The Doris IA was offered together with the Dorisflex A as a new product in an advertisement dated October 1955.[13] The price of ¥6,000 was indicated, but it is not fully clear if this applied to the Doris IA, the Dorisflex A or both cameras.

Lewis mentions a "Semi Doris II" dated 1954, but nothing is known about this possible version.[14] McKeown also mentions a "Doris IIIA", but it is said to be a dual-format 6×6 and 4.5×6 folder, certainly related with the Doris Six.[15]
