That's odd, I've been back and forth with another member that way several times today. Perhaps the management is mad at me. Who knows.
In full frame cameras I don't think you can do much better than your noted selection. For serious inspection work I don't think it can be beat, and in creative photography it's a real beast. I use both Sony and Nikon, preferring a smaller Sony a6000 to the Nikon because of the size and frame rates. There are some trade offs in using an APSC sensor but they are relatively minor for my purposes. I think you made a good call if your wallet can handle it.
I have not needed to upgrade from the a6000 but there will come that time. I've also been looking at the a7 as my next camera. One of the reasons is because it's the required payload for an inspection level multirotor I'm considering, other reasons are simply because it's a darn good camera and Sony has been doing great things for quite some time with cameras and sensors. If Sony wasn't great, why would so many other brands be using Sony sensors
