I purchased (and subsequently sold) a Sony NEX-7 for an overseas trip to Paris in May 2012: it had the best image quality for its size, weight and price. With the 18-55mm "kit" lens, I was able to carry the camera everywhere in my jacket pocket. The Sony sensor has good dynamic range and at 24 MP we can make 11x14 inch prints @ 360 dpi.
Because of their "mirrorless" design, NEX cameras have a very small flange-to-focus distance, allowing us to use other lenses, such as Leica, Nikon, Canon, Pentax, etc. Below are a few samples images.
