Interesting. I presumed Ashahi had its own lens plant...

In a situation like the above, who does what?
Who designs the actual optical charactoristics of teh lens?
Who builds the prototypes? The regular line?
Who quality controls, and where does the coating come in?

IE, is it the design and prototype would be done by Pentax, or Leitz, or
whomever, then given to Cosina/Sigma/etc for mass production? Does it go
back to the mother company to have coatings applied, or do Cosina have
their own machines do it to the Pentax spec?

FWIIW Sigma has produced 28-70 mm lenses for Leica. So they are not the Asian Zeiss 
(Kyocera is) but they can do a good job if they want to. And the workmanship of the EX 
line (like the 105 Macro I have) is really very good indeed. And nobody knows what 
they have made for other brands.
And I still have a suspicion that the Pentax limiteds may be made by Cosina.
All the best!

Because they are not made the same way - Cosina lenses are cheap, Voigtländer lenses 
are expensive, although cheaper than Leica glass.
