We got an excellent reading from Zeiss again.
It may be way too technical for many (or most) but still something well worth taking a look.

Nine rounded iris blades guarantee images with a harmonic bokeh

Happy learning ;)
We may have questions waiting for answers !

The images on page 43 and 44 (described on page 45) is taken with a 24MP FF camera with a Makro-Planar 2/200.

Nikon D3x or A900/A850?

I can't find this lens in ZF mount. Correct?

Is this a new lens for ZA or ZF mounts?

Doesn't it state 100/2 ?
It is the most likely macro planar 100/2 probably used on d3x.
Although , i would be very surprised if Zeiss, as a manufacturer doesn't have some of their lenses available only to other mounts adapted to use with a-mount cameras as well (not available to public of course)

So it does. Perhaps my cravings for a 200/2 ZA made me read 200. :-)

Cool I learned something new. So my 35-70/4's ugly bokeh is due to lens surfaces that have not been polished evenly.

The article also makes me think of the AF 135/2.8. Fantastic bokeh but low contrast wide open and a lot of LoCA.

If they know this, then why did they make the 16-80cz with only 7 blades?
