I don't trust anything I read in a Zeiss press release, because it's so often inaccurate or just silly. However, I would have thought they would at least mention a floating element design if the lens had one (after the 35 mm f/2 fiasco). So it seems the new lens doesn't.
Toothwalker's comments are intriguing.
I still have a soft spot for the old ZF 25 mm, with its phenomenal flare resistance and sharp centre even at full aperture.
