Looks like Carl Zeiss is now just becoming ZEISS in a bid to consolidate brand name and brand communication.
Founded by Carl Zeiss, the brand is often simply referred to as Zeiss. To keep things consistent, Carl Zeiss will now be just ZEISS.
Janne notes that some of the EOS proto pics mentioned simply ZEISS as opposed to Carl Zeiss therefore it wasn’t immediately fake as some implied (as all previous Nokia Carl Zeiss cameras mentioned the full name).
WPC have picked up on this and have an article here saying this news from ZEISS adds credibility to the EOS protos (which btw, I’ve read a few comments here from some guys that speculate certain leaks might have come from Nokia itself. Intriguing).
Cheers Alvester for the tip!
