For Sensor Detectives. GH3 Sensor appears Panasonic's

I asked the Panasonic reps at Photokina and the confirmed reluctantly that the sensor is made by Sony.

That's proof enough for me :).
And I'm sure you won't get any more information by Panasonic on that topic.

Btw. the specs are identical to the sensor of the OM-D.

And once again, why is it so important who makes the sensor of the GH3 anyway ?

In the end it doesn't matter at all.
