FWIW, if you haven't already dropped the cash, don't hesitate to look at the former ComBloc stuff.
The Soviets would put significant money into some of this stuff, because it had military benefits. Some of the older Kiev cameras (I don't know about now, to be honest) were highly regarded as being primitive, but with great optics and tank-like build quality. Many of their optical designs were either stolen from the West, or outright true Zeiss formulas, because when Germany was split, so was Carl Zeiss' manufacturing and research.
The West became known as Carl Zeiss, and the East got Carl Zeiss Jena (CZJ).
Some newer cameras boast Carl Zeiss designed lenses, but they're not produced by CZ nor do they feature T*, the world's foremost optical multicoat. CZJ lenses also did not have T*, but were multicoated.
While this is cameras, I see no reason why other ComBloc optics don't carry the same pedigree.
