Of the Zeiss glass, the 25mm was a rare mediocre lens but to be honest for the price on eBay it is great.
I really am not that convinced about using expensive full frame wide angle glass solely on the GH2.
It can only be truly useful for those who have full frame (or plan to buy one in the future) and a crop sensor camera like the GH2.
If you only plan to use your lenses on the GH2, the Leica/Voigtlander will be just as good, and more compact.
PS, Sara... I'll let you in on a secret. Panasonic provide 90% of the Aspherical elements in worldwide lens production
