yabokkie: with 2 asph elements, this lens looks more like a Sigma and probably it's an OEM from Sigma, and should be as sharp as other Sigma lenses.
I don't think he is too far off. Cosina has made quite a bit for Zeiss, why not Sigma, or maybe Cosina again? And what do you think about the Leica lenses that were made in Canada VS the ones that were made in Europe? I think "Leitz"/ELCan are still making glass for people. Could be wrong.
I hope they take all of their photo apps to the cloud and help create a very useable web based "photoshop" for the masses.
