The German made Zeiss cameras and optics are highly regarded, worldwide, and its like that for ages. Zeiss leading role in optics was a fact, long before the Japanese started to copy Zeiss and many others German companies.
It might be interesting to know that Hubble's replacement, The James Webb Space Telescope optics are designed, integrated and tested by Carl Zeiss Optronics GmbH of Oberkochen, Germany.
Zeiss is probably the only company that provides lifetime transferable warranty for their pro optics and its been like that for many decades.
Absolutely!
