The Praktina System
Praktina FX model DS
The First Generation
Camera Name: Praktina FX
Model Name: DS
Different Versions: 2
Production Date: c. 1953
Estimated Production: c. 1,000
At the Trade Fair in Leipzig, in September 1953, the VEB Kamera-Werke Niedersedlitz released the PRAKTINA FX with its definitive aspect and with small changes compared with the last prototype. New are the eye-level finder with a different shape, the "KW Germany" logo marked on the top of the body cover and the eye-level optical finder with a different edge.
The camera has the mechanism to close automatically the diaphragm of the semi-automatic lenses to the pre-selected aperture, two standard F and X coaxial contacts for bulb and electronic flash units and the name "Praktina FX" stamped on the front. In some cameras of this model the mechanism to control the lens diaphragm is missing.
The Praktina FX was the first 35mm SLR in the world to introduce:
• a mechanism, placed inside the camera body, to control the shutting of the diaphragm to the selected aperture of the semi-automatic lenses
• a single-axis non-rotating dial with shutter speed settings from 1" to 1/1000"
• the capability to use an Electric Motor or a Spring Motor
• the capability to use a 17m Magazine Back for up to 450 pictures
The Praktina sports a set of innovative features that place it remarkably ahead of its time. It took seven years to see a new SLR camera, the Nikon F, with the same professional features.
It is possible to value the high technical specifications reached by this camera comparing the Praktina with the 35mm SLR produced up to 1953: Asahiflex I, Asahiflex Ia, Kine Exakta, Kine Exakta II, Exakta Varex, Exakta Varex VX, Exa, Zenith, Alpa Reflex, Alpa Prisma Reflex, Alpa Alnea Mod. 4, 5 and 7, Rectaflex 1000, Rectaflex Junior, Rectaflex 1300, Praktiflex, Praktica, Praktica FX, Contax S, Contax D, Pentacon, Wrayflex I and Contaflex.
