Camera market is a total sideshow for Zeiss, whose main income stream is from EUV lithography machine lenses, as a partner with ASML -> TSMC.
The iPhone CPU is etched into silicon using Zeiss glass.
These big companies are interested in growth.
They'd rather buy an unprofitable, but growing company, than a profitable but stagnant one.
The Chinese might buy ARRI for the patents and branding.
Only if it stays in German hands will they continue as a cinema camera manufacturer.
That's what I think anyway and I could be wrong, we'll see.
