The Primo has been observed with chrome trimming, but {{McKeown}} also mentions a black variant (calling the black variant "Primo I" and the chrome variant "Primo II", but this is contradicted by the advertisements). The examples observed have an Oscar Anastigmat 75/3.5 or 75/4.5 lens and a shutter with T, B, 1&ndash;500 speeds, marked ''PRIMO'' at the top and ''RAPID-PRESTO'' at the bottom.

The Primo (プリモ) is a Japanese 4.5×6 folding camera made by Daiichi Kikō and distributed by Ōsawa Shōkai in the first half of the 1940s.

Description

The Primo has a horizontal folding body, unusual for a 4.5×6 format camera. The shape of the folding struts is inspired from the Balda folders. The folding optical finder is in the middle of the top plate, there is a body release to the right and a button to the left which simultaneously opens the finder and the folding bed. The advance knob is at the left end and has an arrow to indicate the winding direction. The back is hinged to the right and has a single red window at the top right, protected by a horizontally sliding cover. There are strap lugs at both ends of the top plate, spring-mounted film retaining flanges at the bottom and a screw thread in the middle of the bottom plate. The name PRIMO is embossed in capital letters in the folding bed leather.

The shutter is a Rapid-Presto made by Kinshō, giving T, B, 1–500 speeds. The shutter plate is inscribed PRIMO at the top and RAPID–PRESTO at the bottom. The lens is a three-element Oscar Anastigmat 75/4.5 or 75/3.5 with front-cell focusing, made by Ōki.[1]

Advertisements and other documents

The Template:Kakaku1940 short compiled in late 1940 lists the "Semi Primo I" for ¥121 and the "Semi Primo II" for ¥160, with no further detail.[2]

In advertisements dated December 1942 and May 1943,[3] the Primo was again offered in two versions: the Primo I (プリモⅠ型) with f/4.5 lens (¥136, then ¥157.5) and the Primo II (プリモⅡ型) with f/3.5 lens (¥160, then ¥184.94).[4] The camera was touted as "the smallest of the 4.5×6" (セミ判で一番小さい), with an "ideal horizontal construction" (理想的横位置). The advertising picture is the same in the two advertisements, showing a camera in chrome finish.

The two models are also listed in the "Kokusan shashinki no genjōchōsa" ("Inquiry into Japanese cameras") of early 1943.[5]

Actual examples

Most observed examples of the Primo have chrome body edges and a chrome viewfinder. The f/3.5 lens usually has a silver bezel and the f/4.5 lens has a black one. However one example is known in black finish: it has black painted body edges, a black viewfinder front frame and an f/3.5 lens with black bezel.[6]

Some shutters have an additional RAPID–PRESTO engraving at the bottom of the rim and others do not.

Notes

  1. "Kokusan shashinki no genjōchōsa" ("Inquiry into Japanese cameras"), lens items Lb28 and Lc7. The maker's name is not mentioned for the f/3.5 lens but the attribution to Ōki is likely.
  2. Template:Kakaku1940 short, compiled on October 25, 1940, published in January 1941, type 3, sections 6B and 7B.
  3. December 1942: advertisement published in Asahi Graph (23 December 1942), reproduced in the Gochamaze website. May 1943: advertisement published in Hōdō Shashin, reproduced in Kokusan kamera no rekishi, p. 90.
  4. Sugiyama, items 1225–6, and McKeown, p.&nbsp239, mistakenly say that the model I is black and the model II is chrome.
  5. "Kokusan shashinki no genjōchōsa" ("Inquiry into Japanese cameras"), listing Japanese camera production as of April 1943, items 33–4.
  6. Example pictured in Sugiyama, item 1225.
