I suspected wishful thinking in the belief that it was a Sony sensor. Have you posted this on m43 forums?
Sony sensors = IMX prefix (all sizes - P&S, APS-C, FF), Panasonic sensors/chips = MN prefix... here we have M prefix... so I need help to understand who that is.
And how did you get the shot?
I am using Panasonic GH3 of course.
