The earliest batches of the Ercona were almost identical to the Western Ikonta. This simple model was then developed further in Dresden, and later batches are equipped with a dual format system, allowing the photographer to chose between 6x9 or 6x6 format. These cameras were equipped with two red windows, a removable 6x6 mask in the film chamber and an additional flip-up square mask in the finder.
The Ercona I can be found with Novar (later Novonar) 4,5/110 or Tessar 3,5/105 lenses.
The simplest models have Junior shutters from Gebrüder Werner (GW), with three shutter speeds (1/25, 1/50 and 1/100). Early cameras can be found with Compur shutters, while later models can have either a Tempor or a Prontor-S, all with shutter speeds from 1 to 1/250 sec.

The Ercona II from 1956 was very similar to the Ercona I, but the finder was now built into a chrome top. It can be found with the same Novonar or Tessar lenses as the Ercona I, but only with Tempor shutters with speeds from 1 to 1/250 sec., or a (somewhat rare) Prontor-SVS with speeds from 1 to 1/300 sec.
The Exona was not an export version.
