The Rosen Hand or Rosen Hand Camera is a Japanese 6.5×9cm folding plate camera, attributed to the company Proud and advertised in 1935.[1]

General description

The Rosen Hand has a metal body shows some similarity to the Proud plate folder, to which it is perhaps related. There is a brilliant finder and a folding frame finder made of two parts: an eyepiece attached to the rear and a wireframe attached to the front standard. Above the body is a handle and the folding bed release. Focusing is done via a small wheel placed on the right of the folding bed, with what seems to be a focus lock, and the distance scale is on the left.

Versions

One example is pictured in Sugiyama and Kokusan kamera no rekishi with a Corygon-Anastigmat 10.5cm f/4.5 lens, a Vario shutter giving 25, 50, 100, B, T speeds and no movement ability.[2]

A 6.5×9 plate folder presented as a Rosen has been sold in a Yahoo Japan auction. It is mostly similar to the Rosen mentioned above and it has a Corygon-Anastigmat 10.5cm f/4.5 lens by Friedrich, but the shutter is a Compur giving T, B, 1–250 speeds and the U-shaped lens standard is different and allows vertical movements.

Notes

  1. Kokusan kamera no rekishi, p. 343, Sugiyama, p. 34 and McKeown, p. 804. Kokusan kamera no rekishi mentions one advertisement dated 1935, and the other sources give the same date.
  2. Sugiyama item 1240. A smaller version of the same picture is reproduced in Kokusan kamera no rekishi, p. 343.
