Bah, that's only F/10. The Zeiss is F/4!

The diameter of the front element is what makes a lens expensive.. not really the minimum F/stop number.

The maximum aperture is a function of the size of the front element.

Indeed it is..
It's the focal length divided by the maximum aperture.

That's crazy for still photography.

It's not for sale. It was a special order by one very wealthy client. They're not producing them.

I understand that they won't produce them for stock to try to bring to market, but they did engineer it, and I'm certain they would gladly fabricate another for a customer willing to pony up the dough.

I'm curious about the prototype history of that lens, and to what extent Zeiss may have had prototypes already in development.

<--- didnt read the article beyond a few paragraphs
<----sells Zeiss microscopes

that lens should easily cost over a million to make if the takahashi one I linked to costs $250 with nearly half the diameter.
