I'm certainly interested to see how it performs having owned the OMD originally. I did however swap to the Nikon D600 which although heavier isnt that much larger in practical terms if used with one of the smaller 50mm primes. Both require a bag or shoulder strap niether are going to fit in a pocket, in fact the OMD was too small. The EM1 is larger which I think is important but I think untill the sensor grows people will always knock it. The OMD was great but got limited in darker available light shots, the D600 just has way more going on in the dark. I do however miss the EVF as having a true preview of the finished shot is so handy. Perhaps one day some one will combine all these attributes.
daqk: 1. Too Expensive!2. No Flash?
Pop up flashes have their limitations for sure but they are so handy filing out shadows in daylight shots of faces they should be essential on any walk about camera.
