OMD E-M5 Vs G5?

Kim is not the first one who did a test like this. Amin presented the results of a similar test in August in the mu-43 forum using RAW-Therapee as processor (no g5 support in ACR at that time)

The result is basically the same. For practical purpose no difference when working with RAW between G5 and EM5.

It should be noted that unlike here there was no screaming and shouting after this test.
