| − | == 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. <br>
| |
| − | 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 made 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).
