Editing Sakura Reflex Prano and Idea Reflex

{{Japanese plate SLR}}

The '''Sakura Reflex Prano''' (さくらレフレックスプラノ)<REF> The name "Prano" is sometimes written "Plano" by mistake. The two spellings would be pronounced the same in Japanese, but "Prano" is confirmed by a marking on the [[Sakura Pocket Prano]] and by an advertisement reproduced in [http://www2f.biglobe.ne.jp/~ter-1212/sakura/prano41.htm this page at R.&nbsp;Konishi Rokuoh-sha]. </REF> was the first Japanese SLR, made from 1907 by [[Konica|Rokuoh-sha]], the manufacturing branch of [[Konica|Konishi]] (predecessor of [[Konica]]), and by various subcontractors. It was renamed '''Idea Reflex''' (アイデアレフレックス) in 1910, and was replaced by a different '''Idea Reflex''' model in 1911.

== Origin ==

Some people question the origin of the Sakura Reflex Prano and suggest that it was actually a rebadged imported camera.<REF> Lewis, p.20: the Sakura Reflex Prano "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". The same doubts are expressed about the [[Sakura Honor]], [[Sakura Palace]] and [[Midg]]. </REF> However one advertisement for the Sakura Reflex Prano apparently says that it was "made by Konishi Honten in Tokyo, Nihonbashi", and the December 1911 catalogue by the company says that the Idea Reflex was the result of many years of effort by the company.<REF> Advertisement reproduced in Tanaka, p.94 of {{KKS}} no.10: 東京日本橋小西本店製 (hardly legible), and reprint of the December 1911 catalogue of [[Konica|Konishi Honten]], p.14: 本店が多年の苦心によりて成れる. </REF>

The only picture of the '''Sakura Reflex Prano''' observed so far is a drawing taken from an original catalogue.<REF> Illustration reproduced in Sakai, p.18 of {{KKS}} no.10, in [http://sts.kahaku.go.jp/sts/detail.php?id=1033&key=103310371009&APage=1 this page of the Center of the History of Japanese Industrial Technology], and in [http://www2f.biglobe.ne.jp/~ter-1212/sakura/reflexprano.htm this page of the R.&nbsp;Konishi Rokuoh-sha website]. </REF> It shows an exact copy of the [[Rochester]] [[Premo Reflecting Camera]] (the name "Prano" itself was undoubtedly crafted after "Premo"). The body is made of wood and has the shape of a box. 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 has a focal plane shutter, and one advertisement mentions 1/75 to 1/1200 speeds.<REF> Advertisement reproduced in Tanaka, p.94 of {{KKS}} no.10. </REF> Other speed ranges are reported, with 1/1000 top speed.<REF> Sakai, p.18 of {{KKS}} no.10, and [http://sts.kahaku.go.jp/sts/detail.php?id=1033&key=103310371009&APage=1 this page of the Center of the History of Japanese Industrial Technology]. </REF> The cameras were certainly hand-made one at a time, and these small variations are not surprising.

The Sakura Reflex Prano was reportedly released in April 1907.<REF> Chronology from the official company history ''Shashin to tomo ni hyaku-nen'', reproduced in Tanaka, p.94 of {{KKS}} no.10. The date is simply given as 1907 in Sakai, p.18 of {{KKS}} no.10, in [http://sts.kahaku.go.jp/sts/detail.php?id=1033&key=103310371009&APage=1 this page of the Center of the History of Japanese Industrial Technology], and in the [http://www2f.biglobe.ne.jp/~ter-1212/sakura/11year.htm chronology at R.&nbsp;Konishi Rokuoh-sha]. </REF> Most sources say that it was only available in {{nimaigake}}-size (8×12cm), but at least one source mentions {{tefuda}}-size (8×10.5cm) instead, perhaps by mistake.<REF> ''Nimaigake'': Sakai, p.18 of {{KKS}} no.10, Lewis, p.19, and [http://www2f.biglobe.ne.jp/~ter-1212/sakura/reflexprano.htm this page of the R.&nbsp;Konishi Rokuoh-sha website]. (Many sources say that {{nimaigake}} corresponds to 4×5in, but the actual measurements given in [http://www2f.biglobe.ne.jp/~ter-1212/sakura/11year2.htm#size this page at R.&nbsp;Konishi Rokuoh-sha] do not confirm this.) ''Tefuda'': chronology from the official company history ''Shashin to tomo ni hyaku-nen'', reproduced in Tanaka, p.94 of {{KKS}} no.10. </REF> It was offered with various lenses from [[Carl Zeiss]] or [[Goerz]].<REF> Lists are given in Sakai, p.18 of {{KKS}} no.10, and in [http://www2f.biglobe.ne.jp/~ter-1212/sakura/reflexprano.htm this page of the R.&nbsp;Konishi Rokuoh-sha website]. They disagree on the focal length, the former saying 12.8cm, 15cm and 15.5cm, and the latter saying 21cm. </REF> It was also available without a lens, reportedly for ¥135.<REF> Sakai, p.18 of {{KKS}} no.10. </REF>

The camera was renamed '''Idea Reflex''' in 1910, and some sources specify September.<REF> Kikuoka, p.28 of {{KKS}} no.10, and chronology from the official company history ''Shashin to tomo ni hyaku-nen'', reproduced in Tanaka, p.94 of {{KKS}} no.10. The date is simply given as 1910 in the [http://www2f.biglobe.ne.jp/~ter-1212/sakura/11year.htm chronology at R.&nbsp;Konishi Rokuoh-sha]. </REF> It seems that the catalogue entry for this model was illustrated with the exact same drawing as for the Sakura Reflex Prano.<REF> Compare the drawings reproduced in Sakai, p.18 of {{KKS}} no.10, and in Kikuoka, p.28 of the same magazine. </REF> It is said that {{tefuda}} (8×10.5cm) and {{kabine}} (12×16.5cm) models were introduced, and top speed is reported as 1/1200.<REF> Kikuoka, p.28 of {{KKS}} no.10, mentions 1/1200 top speed and {{tefuda}} and {{kabine}} formats, but does not mention {{nimaigake}}. The chronology from the official company history ''Shashin to tomo ni hyaku-nen'', reproduced in Tanaka, p.94 of {{KKS}} no.10, says that the camera was made in {{tefuda}} and {{nimaigake}} formats. </REF>

The '''Idea Reflex''' was heavily modified in 1911.<REF> The date is given as January 1911 in Kikuoka, p.28 of {{KKS}} no.10, and as August 1911 in the chronology from the official company history ''Shashin to tomo ni hyaku-nen'', reproduced in Tanaka, p.94 of {{KKS}} no.10. It is simply given as 1911 in the [http://www2f.biglobe.ne.jp/~ter-1212/sakura/11year.htm chronology at R.&nbsp;Konishi Rokuoh-sha]. </REF> The new model is mainly known from an entry in the December 1911 catalogue of [[Konica|Konishi Honten]],<REF> Reprint of the December 1911 catalogue of [[Konica|Konishi Honten]], p.14. The page is also reproduced in [http://www2f.biglobe.ne.jp/~ter-1212/sakura/idearef0.htm this page of the R.&nbsp;Konishi Rokuoh-sha website]. </REF> 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}} (8×12cm) and {{kabine}} (12×16.5cm) size.<REF> The chronology from the official company history ''Shashin to tomo ni hyaku-nen'', reproduced in Tanaka, p.94 of {{KKS}} no.10, only mentions {{kabine}}-size but this is an omission. </REF> The text says that No.2 has a revolving back, which is implicitly absent from No.1.
