Adler VI (1938)
|Column in Shinkō Graph August 1938. (Image rights)|
A 6×6cm Adler camera was announced in the August 1938 issue of Shinkō Graph. In the document, it is merely described as a bellows camera, with no further detail. The name is given as "Adler IV" (アドラーIV), an obvious mistake. (The true Adler Four was a 4×4cm folding camera, announced in the same issue of the magazine.)
Another 1938 document reportedly has an Adler VI (アドラーVI型), certainly the same camera, priced at ¥90 with f/4.5 lens and ¥100 with f/3.5 lens. The document lists various other Adler cameras, and offers ten-month payment plans.
Possible surviving example
This early Adler VI, for which no original picture is available, is surely different from the horizontal folding camera that was sold in the early 1940s. It probably corresponds to a rebadged version of the First Six by Kuribayashi. One surviving Adler 6×6cm camera, clearly based on the First Six, is pictured in an article by Tanaka. It has the name Adler embossed in the leather covering at the front, and a folding optical finder for square exposures. Its shutter is a Peerless (5–150, B, T), marked PEERLESS at the bottom, with the round AKK logo of Asahi Kōgaku Kōgyō on the right. The lens is an Adler Anastigmat f/4.5.
Adler Six (early 1940s)
The Adler Six sold in the early 1940s is a horizontal folding camera, copy of the Ikonta 6×6. There is a folding optical finder in the middle of the top plate. The film is advanced by a key at the left end — as seen by the photographer. The body release is on the right and the folding bed release is on the left, next to the viewfinder. There are strap lugs at both ends of the body. The back is hinged to the right, and locked by a sliding bar on the left.
The shutter is a Roico I (T, B, 5–200) with setting lever. The rim is engraved ROICO I at the bottom and the speed settings are inscribed T, B, 200, 100, 50, 25, 10, 5 in that order.
The camera exists in two versions: the Adler Six I with a Ricoh Anastigmat 75/4.5 lens, and the Adler Six II with a three-element Ricoh Anastigmat 75/3.5 lens.
Advertisements and other documents
The official list of set prices compiled in October 1940 and published in January 1941 has an "Adler Six" for ¥79 and an "Adler Six II" for ¥94. It is not known for sure if they correspond to the camera advertised in 1942 or if they are a continuation of the 1938 model mentioned above.
The Adler Six still appears in the government inquiry listing Japanese camera production as of April 1943, with the Ricoh f/3.5 lens only.
The only surviving example known so far is an Adler Six II, pictured in an article by Tanaka and in the Ricoh official website. It has the Ricoh Anastigmat 7.5cm f/3.5 lens no.10668.
- The name "Adler" was clearly used to demonstrate Japan's alliance with Germany. During the war period, Riken often used such names (they also sold a Heil camera), or other "patriotic" names.

- This page of the Ricoh official website says that the shutter is a Roico II with B, 10–200 speeds, but this is probably a mistake.
