Latest KMZ Zenit, with motor drive and new ergonomic body. It is a much bigger camera than the 412LS or Automat-series.
The frame counter is an LED readout which is quite a step up in Zenit electronics.
Full range of shutter speeds from 1 to 1/2000 + B and full Auto.
KM+ is actually a corrected & repaired version of KM, which unfortunately had many faults.
