San Giorgio was a camera-maker in Genoa for a few years after the Second World War. The company was founded in 1905, to make vehicles, but soon (presumably because of the First World War) turned to making optical products including gunsights. After the Second World War, the company designed some cameras in an effort to develop civilian business. Only the Janua Leica-copy was made in significant numbers (a few thousand, though the late Janua S has serial number 451,xxx).
- Parva: a camera for 16 mm film, made only in sample quantities.
- Janua: a Leica copy
- Safo: a camera for 24x24 mm on 35 mm film.
