If you look at the Zeiss category on this page, you will only see reports about price increases, discounts, and the fact that Zeiss has not announced any new photography lenses in more than three years. Zeiss is now building its first factory in China, but there is no word on any lens development or manufacturing yet:
"Zeiss, the German optical giant who entered the Chinese market 65 years ago, is breaking ground on a new factory in Suzhou, China. The factory will be Zeiss’s first self-built factory in China, which marks the company’s confidence in the market as it deepens its roots.
The Suzhou factory, with a total investment of $25 million (approximately RMB 181 million), will incorporate the microscopy division's B&C global product center, including product management, R&D, production and global distribution, as well as part of the industrial measurement division's global production base and the Greater China customer and solutions center.
In addition, Zeiss' Medical Division will also add the production of Class II medical devices, such as operating microscopes and ophthalmic diagnostics, as well as expand the global procurement business of Zeiss' headquarters and divisions. In the future, the new site will also introduce other business segments of the Group, according to IT ZhiJia." (source: Pingwest)
