Sakura Reflex Prano and Idea Reflex
The Sakura Reflex Plano (さくらレフレックスプラノ)[1] was the first Japanese SLR, made from 1907 by Rokuoh-sha, the manufacturing branch of Konishi (predecessor of Konica), and by various subcontractors.[2] It was succeeded by the similar Idea Reflex in 1910, then by a different Idea Reflex model in 1911.

The Sakura Reflex Plano and Idea Reflex (1910)
The only picture of the Sakura Reflex Plano observed so far is a drawing taken from an original catalogue.[3] It shows an exact copy of the Rochester Premo Reflecting Camera, with a box-shaped wooden body. There is a folding bed at the front; the lens standard is mounted on bellows and slides out of the main box. There is a large viewing hood at the top, further lengthened by trellis struts. A lever is visible on the right-hand side of the body, perhaps used to raise the mirror and trip the shutter.
The camera is said to have a focal plane shutter, initially giving 1/75 to 1/1200 speeds.[4] Other speed ranges are reported, with 1/1000 top speed.[5] The cameras were certainly hand-made one at a time, and these small variations are not surprising.
It is said that the Sakura Reflex Plano was only available in 4×5in format, called nimaigake (二枚掛) in Japan at the time.[6] It was offered with various lenses from Carl Zeiss or Goerz.[7] It was also available without a lens, reportedly for ¥135.[8]
The camera was renamed Idea Reflex in 1910.[9] It seems that the catalogue entry for this model was illustrated with the exact same drawing as for the Sakura Reflex Plano.[10] It is said that tefuda (8×10.5cm) and kabine (12×16.5cm) models were introduced, and top speed is reported as 1/1200.[11]
The Idea Reflex (1911)
The Idea Reflex was heavily modified in 1911. The new model is mainly known from an entry in the December 1911 catalogue of Konishi Honten,[12] where it is called "Idea" Reflex Hand Camera (アイデヤ、レフレックス手提暗函). Two versions are listed: the Idea Reflex No.1 (壹號) in tefuda size (8×10.5cm) and the Idea Reflex No.2 (貳號), in nimaigake (4×5in) and kabine (12×16.5cm) size. The text says that No.2 has a revolving back, which is implicitly absent from No.1.
The pictures show box-shaped SLR cameras with bellows and a large viewing hood. It seems that No.1 has no folding bed but large rack-and-pinion struts driven by a wheel on the photographer's right. No.2 has a folding bed and a front standard sliding on rails with a smaller rack-and-pinion device. Various shutter controls are visible on the right-hand side plate, including a winding key at the top. The picture of No.1 shows more controls on the right, and a table of shutter speeds. The picture of No.2 shows a leather handle on the right, less controls and no shutter speed table.
The cameras were available with or without a lens. The listed lenses are featured in further pages of the same catalogue, showing the Carl Zeiss lenses imported by Konishi.[13] The prices are summarized in the following table.
body version | No.1 (tefuda) | No.2 (nimaigake) | No.2 (kabine) |
lens option | |||
body only | ¥95 | ¥135 | ¥175 |
Carl Zeiss Tessar Series Ic | 150/4.8, ¥176 | 180/4.5, ¥235 | 210/4.5, ¥300 |
Carl Zeiss Tessar Series IIb | 135/6.3, ¥155 | 180/6.3, ¥198 | 210/6.3, ¥281 |
Notes
- ↑ The camera is sometimes called "Sakura Reflex Prano". The exact Roman spelling is unclear, but "Plano" seems more plausible.
- ↑ Lewis, p.20, however says that the Sakura Reflex Plano "so closely resembled the Western originals there is some question whether they were really Japanese copies, or whether they were imported cameras sold under the Sakura name".
