Introduction
The Sirene is series of plate cameras produced by ICA in Germany. They were made between 1914 and 1926. The most common model is the Sirene 135. All models are of the folding plate design.
Specifications
The Sirene 135 has a Extra-Rapid-Aplanat "Helios" lens. It's a two element lens, with both elements screwed into either end of the shutter. Its focal lenth is 13cm with a maximum aperture of f/8. A small lever under the lens allows a stepless setting of aperture. A series of 8, 12.5, 18, 25 and 36 is marked on the front plate.
The unnamed shutter has Z, B, 1/25-1/100s setting. It's a two blade shutter. The Z (Zeit) setting corresponds with the T (time) setting. The two five pointed stars at either end of the shutterspeed series may suggest it was made by ICA itself. The shutter can be tripped by a lever or by cable release.
Variations
The Sirene was made in two formats; one for 6×9cm and the other for 9×12cm glass plates. The Sirene 135 was amde exclusively for the 9×12 size. (When actually measuring the inner size of the glass plate holders, 9.1×11.6cm would be image format).
