| Praktica BX-SystemProduction period: December 1987 to December 1990 Number of Models: 4 Number of produced items: 201,797 responsible constructor: Herbert Welzel, Rolf Seifert
With the cameras of the BX-series a new camera-generation was born which leads to a simplification of the production-process and some new functional features:
The name BX was used to differentiate from the B-series cameras which don't use DX-encoding. Between 1987 and December 12, 1990 altogether 201,797 BX-Praktica's were produced. The design was developed by Manfred Claus and Reinhard Voigt in 1986/87. The BX 20 the first camera of the BX-line were produced since December 1987. On the domestic market films with DX-encoding were no available. But the TTL-flash system and the available winder induce a very good establishment of the new camera on the market.
optical path for aperture setting (1), for reflex picture (2), for TTL-light metering (3) and for TTL-flash metering The BX 10 DX was a potential cheap model which only allows automatic work comparable to the B100/BCA/BCS-cameras from the B-series. This conception was abolished. The sample series is a desired collection object. The BX 21 has a comparable fate. The BX 20s was the last model of this camera line. With a new ergonomic design, developed by Manfred Claus in 1989, and the automatic-comfort this camera was the battleship of the latest Praktica-SLR development, but a serial production under the conduction of the traditional Pentacon Dresden was not achieved.
