GH3 has most likely Sony sensor
If it was a Panasonic sensor, this simple question would have a clearer answer rather than "No comment"
EOSHD: Is it a Panasonic sensor? So it is not a Sony sensor?
Inoue: Ah no comment!
EOSHD: Because I noticed this is a standard four thirds sensor, because the GH2 had a multi-aspect ratio sensor. The GH3, does that have multi-aspect ratio sensor?
Inoue: This is a priority for imaging quality, our big priority is keeping that image sensor quality.
