The Panasonic GH3 Gets DXO MARK'ed, comes out as very similar to the Olympus E-M5, do they use the same sensor?

"The Panasonic Lumix DMC GH3 is a very good camera, among the best tested by DxO Mark in this format. It is small and light and will make an excellent camera to travel with and fulfils all of the requirements that a serious enthusiast is likely to have. However, it is pricey for a hybrid and it has competition from several directions. The Olympus is even smaller and lighter and scores slightly higher but it does lack a viewfinder. For a similar price you could be buying either the Pentax K 01 or the K-5 IIs, both of which have scores consistently higher than the Lumix but obviously with the overhead of a bulkier and heavier piece of

equipment to carry. You could also be looking at the Sony NEX-6 which is the closest technically, scores better and is cheaper. There is no escaping from the conclusion that the Panasonic Lumix DCM GH3 is going to be the ideal camera for some people, but for others the better choice would be some more detailed research."

"The brand that scores equal to, or higher than the Lumix, but has the same lens mount – Micro 4:3 – is Olympus with the PEN E-PM2 at DxO Mark score of 72 and the OM-D E-M5 which scores 71. They have virtually the same color depth, fractionally lower Dynamic Range and fractionally higher low light performance. If you read through the other specifications they match one another almost point for point except that the Olympus PEN E-PM2 has no viewfinder and the screen is fixed, without tilt, though the OM-D E-M5 does. Both the Olympus cameras are cheaper, the PEN E-PM2 is nearly half the price, so the viewfinder may be a sacrifice worth making for a photographer looking for a really compact system camera. It is worth noting however that the measurements for both the Olympus cameras did show significant variance between the measured ISO and the Olympus’s stated ISO, around a full EV, since it appears to be consistent it is something that you could easily work around but it is there nevertheless."
