The Kadera (カデラー) is a Japanese 4.5×6 folding camera, which was distributed by Ōmiya Shashin-yōhin c.1939, and about which very few is known. (The name Kadera was also used for a 75mm f/3.5 three-element lens made by Gojō — successor of Kajiro Kōgaku — and mounted on the Semi Kinka in 1943.)[1]

Description Edit

The Kadera camera is a vertical folder, with three-part folding struts inspired by the Ikonta 520. There is a folding optical finder, maybe of the Newton type — its front part folds over the rear one. The film is advanced by a knob at the bottom right, as seen by a photographer holding the camera horizontally. The release of the front door is at the top right, and the main release is on the shutter itself. The back is hinged to the left, and retained by a latch on the right, covered by a small handle.

The shutter is chrome-coloured and reportedly gives 25, 50, 100, T, B speeds.[2] It is certainly of the everset type, with the release lever directly protruding on the side. The name KADERA is barely legible at the top of the front plate on the only available picture. The lens is reported as a Kadera 75/4.5.[2] It was perhaps made by Kajiro Kōgaku, as the later Kadera f/3.5 lenses.[3]

Commercial life Edit

The Kadera camera was featured in the new products column of the January 1939 issue of Asahi Camera.[2] The document briefly describes the camera, and quotes the price of ¥48. No other document mentioning the camera has been found, probably indicating that its commercial career was very brief. No surviving example has been observed so far.
