Production stopped and being discontinued are completely different things. Production is done in batches, it's not like they are making them all the time. The frequency of production batches is determined by how fast the stocks are exhausted, which in case of the ZI, is very slow. Anyhow, all film cameras will be discontinued sooner or later.
