Zeiss is a well known brand name from the company named after it’s founder, Carl Zeiss AG. According to the Ziess.com blog the company is changing its name to Zeiss to create consistency across its brand communications.

We’ve seen leaked images of the camera plate on the EOS that were branded with both “Zeiss” and “Carl Zeiss”. Some have thought the images with the Zeiss label were fake.
