One of my early forays into small, mirrorless cameras was a dip into the Nex line from Sony. The Nex 6 was a pretty decent body with a 16 megapixel camera but my favorite was the Nex 7. The finder was good, the dual dials were good and the low ISO, 24 megapixel performance was great!
There were a few downsides that led me to move on. One was the horrible state of the menus in those two cameras. It was sheer chaos. And the main issue I had with the Nex-7 was its temperamental interaction with various wider lenses. Magenta splotches were rampant and the edges of most legacy wide angles were soft. When you piled on with lots of noise at 800 ISO and above you essentially were working with a compromised camera. That being said, it was a nice shooting machine if you stuck to normal and longer lenses and worked in the same, basic fashion most of the time.
I've recently bought a Sony a6000 and an a6300 and I'm loving them. The menus are much better and the sensors are leaps and bounds better. My one wish? I'd love body with the dual dials we had on the Nex-7 camera. Those felt great and were quick and functional. It was an elegant design.
