That is the ranking of the sever testers form the German “Stiftung Warentest“. As you see the Panasonic Gh3 ranked as current best DSLR+Mirrorless System Camera. Also the compact cameras from Panasonic and Olympus are on top of the list. Quite an astonishing result! That said there is no such thing as a perfect ranking and testing. It all depends from what you need :)
P.S.: In Germany a lower score = better quality.
And finally we have some clue when the GH3 will ship at Amazon US (Click here). On Sunday March 31!
