OK, time for some discussion re. EM1 and GH4. I would like to limit this comparison to stills and ruggedness. I own both Pany and Oly lenses and bodies so I have been able to form some personal preferences based on a fair test. I am ready to move on to either the EM1 or the GH4 based on your experiences. Customer support is not a criteria nor is price or ergonomics.....only the ability to record a still image and the quality to survive professional use. HAVE AT IT!!!!!
