The Panasonic Lumix DMC-GH3 is a good performer: scoring 71 overall in the DxO Mark testing it is joint second of all 4:3 cameras that have been measured. The top scorer and the camera that matched it are both Olympus, the Pen E-PM2 at the top and the 2.
Color depth at 22.7 is excellent, Dynamic Range at 12.4 EV it best in class and ISO at 812 is only just behind the two Olympus cameras.
Being very good should be expected, the Panasonic is the most expensive Hybrid 4:3 and among the most expensive of all 4:3 cameras, but if you group the 4 highest priced, 3 from Olympus and the Lumix the scoring now favors the Panasonic.
