The Sigriste camera was made c.1899 for the Swiss painter Jean Guido Sigriste. The magazine camera with rigid tapering body contained flexible bellows, fixed at the front of the camera and tapering to a slit in the focal plane. A combination of the width of the slit and spring tension gave a wide range of expsoure times from ¼0 to ½500 second in nearly 100 steps. Auer (1989) describes the 9 x 12cm. model as 'the most performing and the most prestigious of the family'.
The camera was the subject of various patents including British patents 24567 of 21 November 1898 and 12180 of 10 June 1899 granted to J. G. Sigriste. The former related to the shutter mechanism and the latter to the changing box, roller slide and shutter associated with the camera. Both patents illustrate the Sigriste camera.
