Tian Chi
The Tian Chi is a Chinese near-copy of the Contax F, that was developed by the Chang Chun Optical Research Institute in 1959. Only ten cameras were made, and two of them are thought to have survived.
The Tian Chi has a special breech lock mount and a 56mm f:1.9 lens[1] with automatic diaphragm. In addition to the lens mount, they externally differ from the Contax F mainly by the shape of the top housing above the prism, that is engraved with a triangular logo.
Notes
- ↑ StDenny says that the lens is focused from 6m to infinity. Either it is a typo, or the lens barrel is experimental only.
