We have two new reviews at DC.watch (Japanese with google English translation) and Akihabaranews (in English).
For Akihabara the GH2 is an “impressive upgrade!” and “the [shoplink 14826]GH1[/shoplink] was and still is an incredible All-purpose Camera that kicked some serious ass to other big names including Canon or Nikon. The [shoplink 16254]GH2[/shoplink] just proved to us how far ahead Panasonic is in this field. As a GH1 owner I must admit that I struggled to get used to the GH2 new button layouts but the improvement made on this camera are really worth the hassle.”
DC.watch wrote a less emotional but more detailed review with many Image samples you can download.
P.S.: Still no news about the GH2 availability in Europe and US.
