The Vostok 9 x 12cm camera was produced in small quantities by Novosibirsky Pribori Zavod (PRB) in Novosibirsk between 1948 and 1949. The standard lens is the Industar-51, which has a focal length of 21 cms and a maximum aperture of f/4.5. Unlike most Soviet-made cameras, the Vostok has a comprehensive range of movements. The front panel has rising and cross-front as well as swing and tilt. The back of the camera also has swing and tilt and is rotatable through 360 degrees. The double dark-slide are made to take either glass plates or sheet film. The year of manufacture, factory logo and serial number appear on the lower lens panel clip.
