The over-looked pioneering SLS's were the Praktina's. the first full system camera with a motor drive, also the early East German Contax SLR's.

It's also forgotten that the first SLR with TTL metering was in fact the Prakticamat, the Pentax Spotmatic was anounces first but went on sale after the Prakticamat.

Edixa's were quite a bit after the East German cameras.
