From Sept 7th's 4/3 Rumors' site:
It took long time to get reliable infos about the upcoming Panasonic GH1 successor. We already told you that the Panasonic GH2 will be announced on Tuesday September 21 (the first day of Photokina).
And finally we know the resolution of the new sensor!
The GH2 will have a new 18 Megapixel multi aspect sensor. Like the Canon 7D and Canon T2i (550D) this is the highest resolution sensor available for non-fullframe cameras (APS-C or FourThirds). But because it is a multi-aspect sensor the effective resolution will be 16 Megapixel. It is the highest resolution sensor ever used for a (Micro-)FourThirds camera. The new Olympus E-5 (to be announced on September 14) will not use that sensor.
We need your help to confirm the other GH2 camera specs we received. If you know “something” feel free to share your knowledge using the contact form on the right sidebar (you can avoid to give me your name or email address if you want to keep yourself anonymous). Or contact us at [email protected]. Thanks!
In the meanwhile the GH1 is becoming cheaper and cheaper almost eveywhere (Click here to check the current price). But keep in mind that the Gh1 hack doesn’t work anymore with the newest Panasonic firmware!
