Late 1970s DSLR camera Fuji STX-1
The Fujica STX-1 was sold by Fuji in the late 1970s and early 1980s and was an entry-level DSLR camera at the time. It effectively replaced the Fujica ST605n, replicating most of the camera's specifications, but replacing the M42 thread of the ST605n with a new Fujinon X mount lens mount. It was introduced to the United States in 1979. It is also known as Tengzhong MPF105X. The focal plane shutter is mechanical, with a maximum speed of 1/750 second and flash synchronization of 1/60 second.
