I am using a Sony NEX-6, which was discontinued over a year ago. I am quite pleased with it, including the ability to adapt old manual-focus lenses to it.
There are drawbacks, though. There are certain shooting modes that can't be used together, such as self-timer and bracketing. In addition, it came with a kit lens (16-50mm f/3.5-5.6 PZ OSS) that has serious light falloff at all focal lengths and very serious barrel distortion at the wide angle end. If you only shoot JPGs, in-camera software corrects those issues, but if you shoot raw, you don't really want this lens.

P.S. The most recent several pages of my gallery are shot exclusively with this camera.
