I can't really recommend Sony any more than I do today. It's easy to use, offers a lot of latitude on highlights and shadows, and works with my off camera flash system. When I got the A7RII I was a little worried that I had gotten an impulse buy. Pre-ordering a new camera that has not been through the public ringer is risky to me.
I had been burned in the past with Nikon with going with the D600. The camera was my first full frame, it took amazing photos, and I was in love with it for about 6 months. The issues I had been warned were oil spots leaking onto the sensor. I'm usually reluctant to the hype or the issues first generation technology has, it's more the 1% but this time I fell into that threshold.
I was able to resolve it with Nikon and get a D610 sent over, but after I shot the Sony I just saw what a mirror less, compact, full frame camera could do and I was hooked. Put the small, lightweight FE lenses on there and you have a travel friendly system that produces the same quality pro-level images you'd expect as a working professional.
The image above was shot in our house, using just the string lights. To capture the fast movement of the kids and myself moving from camera to my position as subject, I used around 8000-10000 ISO. 5-10 years ago this was unheard of, this image would not be usable. Today it's not a big deal, got the shot, posted, and everyone loves it.
Thank you Sony for your wonderful products, other cameras are trying to catch up, keep on innovating.
