I decided to spend a small inheritance I had on lenses, figuring that it was better to enjoy what the money could do, and I don't think it was a bad investment. My pride and joy is a Dallmeyer Super Six 8 inch monster, which was expensive, but it is worth a lot more than what I paid for it. I loved the Nikon D800e that I had, which was stolen in China. I thought about getting another Nikon, but since I had a collection of vintage lenses that I had been using on a little crop sensor Sony NEX, I decided to go for the A7RII, since I did want FF with those lenses.
In terms of image quality, I find the Sony every bit as good as the Nikon, with a few advantages in terms of using it with vintage lenses. I was not a fan of mirrorless, but the Sony has convinced me for a number of reasons. I can also shoot great video on the sly, which is a big advantage in my work doing investigative stuff.
There are things that get me crazy about the Sony. The handling is nowhere near as good as with the Nikon, and it occasionally suffers firmware glitches. It is agonizingly slow to clear the buffer and to preview and magnify shots. I hear the A7RIII is better for that stuff. But actually, much as I adore a good OVF, the EVF on the Sony is good enough for critical focusing, with the added benefit of magnification for critical focus, which is especially good with many vintage lenses, where one has to decide between contrast and sharpness in the details. And OMG, the in-body stabilization is a dream come true, and not only for video. If I were doing sports it would definitely be a DSLR, but for my vintage shots the mirrorless is better hands down.
I also do a lot of extreme HDR stuff, and that really tests a sensor, I have found, and the A7RII looks great in that department. I do miss the feel of the Nikon, but I have a lot of respect for the Sony, and now I wouldn't go back.
