Hi Dennis,
The first camera I was attracted to was the Samsung NX11--except I thought it was an NX10, which is selling cheaply here. I read the reviews but they were for a NX10, and they made me cautious...The NX11 seemed like a small jewel in my hands! I liked the EVF, the size of the camera with kit lens, and the availability of a modestly priced moderate telephoto zoom. Regrets? Didn't see a review of the '11.
The Sony has been well reviewed. I really enjoy the higher ISO performance, and images made at higher ISO were attractive to me. I bought one. Regrets? Sony doesn't have an affordable, moderate telephoto zoom that I'm aware of. And the 18-200 is made of unobtainium! I simply can't afford that lens. I know what people are saying about the NEX5 menu functions, and difficulty accessing common settings; however, it's good enough for me.
First trial, literally, was outside, after dark in a scene lit with street lights in a small town. Frankly, the photos I got blew me away! They were taken hand-held. My monopod was safe at home, unfortunately.I tried flash, but results in a camera assigned nightime mode were far superior.
I have no regrets selling my LX5. I do regret giving up on my G11, after the internal memory holding Date/Time failed in the 2nd camera I had. I considered a G12, but wonder whether this issue was corrected.
