Not doughting what you say, but where is the source of your information?
Combination of sources including Wikipedia, Zeiss, Cosina and Sony websites, the manual and warranty card in the box for the one ZA lens I own, DPReview, Dyxum and other Sony/Minolta websites. For the Hasselblad lenses it's easy, they state 'Made in Germany' right on the lens (as does the ZM15 and ZM85/2)
While Sony does rebadge some lenses, they're all Tamrons (and Sony owns a piece of Tamron, around 11% IIRC). Sony has significantly more lens production capacity than Cosina does and a pre-existing business relationship with Zeiss including exactly the production relationship that I'm claiming for the ZA's. Given that Sony has been building Zeiss-branded/designed P&S and video lenses for a decade or more, longer than Cosina has, and has significant SLR lens production capacity of its own, inherited from Minolta, the idea that Cosina does the production of the ZA lenses makes little sense.
Remember, Cosina and Zeiss got together specifically for M lens production and at the time only two companies existed which had the tooling for M mount lenses, Cosina and Leica AG. The ZF line came later, around the same time as Sony took over the A mount line in fact (the first ZF lenses were announced in January 2006, the A100 in June 2006).
