Early Koilos
The Koilos is a German three-leaf shutter. It was the first leaf shutter developed by Gauthier, introduced in 1904. It needed cocking and used a leather break to regulate speeds.
Cameras equipped
- Murer's Express
- Pocket Idea A1 (1911)
- Lily (1909–11)
- Noble
- Pearl No.4 (1911)
Later Koilos

Various Japanese cameras of the early 1930s are equipped with a different Koilos shutter. This Koilos shutter is self-cocking, and tripped by a lever attached to the front plate. The speeds (25, 50, 100, B, T) are selected by a wheel at the top. There is a thread for a cable release on the side, and a thread and needle release under the lens. This Koilos shutter was perhaps made by Gauthier, but this is unclear.
The Koilos shutter mounted on the Nifca-Dox by Nichidoku (predecessor of Minolta) has a peculiar octagonal casing and slightly different controls. It was perhaps not a genuine imported shuter, and at least one source says that it was "clearly made by the company itself".[1]
