My final thoughts on the Samsung system is I believe they far behind their competitors and have lost their way somewhat with the new Galaxy NX. The retail price of €1000+, I don't believe they'll sell too many. They should invest a lot in the camera AF system and get some weight into the cameras themselves. They just feel too plasicky and light.
I personally will not be investing in this system, and I think the NX10 and it's lenses will not be in my inventory much longer. Maybe I can find a new home for it where it will be much more appreciated than by me at present.
