The Italian blog Lucidistorte had a meeting in Milan with Mr.Uematsu from Panasonic. In that meeting Mr. Uemtasu unveiled that the new 12-35mm f/2.8 X lens will be announced on may 21th! Apparently Uematsu told them to not officially publish that news but the Italian blog wrote the news anyway :)
Uematsu also said that the 12-35mm f/2.8 is produced in the Panasonic Yamagata Plant in Japan and matches the quality of the Leica lenses! It has nano surface coating, power OIS. powerzoom.
As you know also the Panasonic G5 will be announced so I guess there is a fair chance that the rumor is real! Stay tuned on 43rumors! And don’t forget to follow us on facebook too (Click here)!
P.S: Panasonic soruces told me the lens has not a f/2.0 paerture like the Olympus [shoplink 25320 ebay]14-35mm f/2.0 (Click here to see them on eBay)[/shoplink] becuase a) it would make the lens a lot bigger 2) lot more expensive.
