Well, I ended up with two cameras instead of one. I discovered I loved shooting with a small camera with the NEX5. But still love shooting with a big-*ss camera. So, I ended up going with a used Sony a99 to work natively with all my a-mount lenses, especially the Tamron 150-600...and picked up an a6000 to carry along with me for landscape and macro shots. So, I can now carry two cameras around! The a99 is fabulous. As a used, older model camera, it is perfect. Reasonably good at everything, still lots of good lenses out there for cheap, and it looks to be a pretty durable camera. Feels solid. Also allowed me to switch over to back-button focus. Here's some shots from this past Sunday's hike around Exton Park. The a6000 is a fun and great-looking camera. It can also hook up to all my old a-mount lenses with an adapter. Fits nicely into my pockets or on a Peak Designs Capture Clip on my backpack while I hike.
I think I've become a discontinued Sony fanboy. The household collection consists of an RX100, NEX5, a6000, and the a99...all of which are discontinued, but totally usable cameras.
