The demand to this cameras was extensive. On this basis some changes and special models were produced. Additionally to the following variations some other types, for example for the market in the Netherlands were produced.

During March 1968 a new interesting camera were, the Praktica PL electronic were presented. The Praktica PL electronic was the first SLR with an electronically adjustable shutter speed. Using a electronic circuit with different resistors were used for the adjustment of the shutter speed. The shutter speed was realised using a rubberised focal-plane shutter using switching magnets. The time-line was geometrically with a range between 30s and 1/500s in 14 steps. Without battery a mechanically realised shutter speed of 1/60s realises the further work. The expensive wattache and the expensive tuning of the assembly force the end of production in 1969.
