You
are wrong.
Carl Zeiss is fully owned by
Carl Zeiss Foundation. Sony is a mere licensee.
Leica is also not
owned by Panasonic, which is just a mere licensee too.
Please back your arguments with facts, not perceptions.
Samsung, Sony and Panasonic are making their own lens now. Panasonic have managed to shrink kit lens into a pancake with their
Lumix G X Vario PZ 14-42mm F3.5-5.6 OIS pancake. Sony and Samsung lens are no pushovers too. So I'm not quite sure what you mean by camera makers are still most important. If tomorrow, all the camera makers go bankrupt or are bought over by Google or Apple, new cameras will still be pushed out by the remaining.
Technology is transferable, even expertise in making glass. It's all about innovation, and who appeals to the consumers most with their offerings. I dare say that the traditional camera makers like Canon, Nikon, etc are upping their game (Pentax Q, Pentax K01, Canon G1X, Nikon J1, upcoming Canon mirrorless model), because they need to defend their market share against the innovations that 'traditionally electronic companies' like Sony and Samsung are bringing in, like SLTs and MILCs. The lines are blurred btw these companies now.
The beneficiaries ? We the consumers.
So learn to appreciate and respect 'traditional electronic companies', and not make disparaging remarks and say half-truths abt them.
