I´ll run my own test when they hit the store. I don´t think dpreview develops their RAW files with stock photography in mind.
The small Nex5 gives excellent files. I hope the new sensor is even better.
But we will see.
I think dpreview mostly just shoots jpgs unless its a test chart. Somehow they make even the best cameras look average in the sample images they put up.
That makes it even worse, since every camera applies noise reduction when shooting jpeg. Those images have lots of noise at iso 200.
