The Porst FX 4 is a SLR camera. It was built from 1968 to 1975 by VEB Pentacon in the GDR. The 35mm camera was intended for the West German market and was offered in the East under the name "Praktica PL Nova I B".
The lenses of the Porst FX 4 can be easily interchanged. This is possible trough the M42-Gewinde. There are many interchangeable lenses available for the M42 mount. The M42 lens mount was developed by Carl Zeiss in Jena (Germany). Zeiss, Pentacon and Pentax were among others major manufacturers of M42 lenses. The Porst FX 4 has no autofocus. It is manually focused.
The camera has a built-in light meter on top of the lens. This is a selenium exposure meter, which does not need electricity for the measurement but can lose accuracy over the years. This can be corrected by setting the ISO value according to the deviation.
The shutter speed and aperture can be selected by the photographer. The Porst FX 4 has a bulb mode, for example for long exposures. The shutter can remain open for a variable time and expose the film. An optional external flash can be used via the provided PC flash socket.
