Zeiss has taken the remarkable stand in stating (in Q&A fashion) that
it believes that the lenses will outperform those already on the
market (I assume that they were talking about Leica et al). That's a
pretty big statement to back up. I would imagine that it might take
more than a month of R&D to design and construct a bevy of those
lenses.
