Hi,
As far as I know Schneider and Leica is German. Hasselblad is sort of interesting it's owned by a Hong Kong firm but is managed from Copenhagen in Denmark. There are different issues, that you need to keep apart:
1) Production
Leicas are built in Germany and Hasselblads in Sweden. Parts can be produced anywhere. Hasselblad lenses and most of the camera is actually built by Fujifilm, but final assembly is done at Hasselblad.
Regarding Leica M and R series are German built, the others are mostly built by Panasonic.
2) Cooperation
Leica cooperates with Panasonic, Zeiss with Sony and Cosina, Hasselbald with Fuji. Some lenses for Sony may be Zeiss designs but produced by Sony. Cosina makes most affordable lenses for Zeiss, but Zeiss in Germany may be building the most demanding lenses. Zeiss does manufacturing in Germany.
3) Branding
Firms like Cosina can build lenses for different demands. They have acquired the Voigtländer brand. They use Voigtländer names to separate high quality products from lesser products.
Samsung uses the Schneider brand for its lenses coming from Pentax. Pentax itself belongs to the Hoya/Tokina group.

I've heard that Voigland is now Cosina (Japan), Schneider is now Samsung (Korea), Hasselblad is now Evergreen (Taiwan), Leica is ... who?
Any of these legendary Germany brands still real Germany company?
