Reed,
A couple more things came to mind as I'm reading the owner's manual for the mark ii to learn the new features and changes (wait 'til you see what this thing can do with tracking AF, truly remarkable!)
Here's the main advice for you on this post: Before I made my final decision on the a77 last year, I downloaded and read through the owner's manual of my top three choices, then went to a Best Buy and Costco to feel them up. I still think you should objectively consider several models, and TRACK YOUR RESEARCH RESULTS to make an informed decision. Though I am biased toward Sony, I didn't start out that way, but thought I'd end up in a Canon. I could easily live with a Canon 7Dii (but I'll never admit that to a certain dear friend of mine, a real Canon aficionado). The problem with the Canon is it costs twice what the a77ii does (for a comparable camera; it is indeterminate which might get the top spot)and there are no inexpensive, quality legacy lenses available, like the Minolta
et al for Sony.
Nevertheless, your initial post reminded me much of myself when I was wading through the swamps of countless makes & models and all the stern opinions. You want to use a camera pretty much how I use mine, and if you want to keep something in the bank, this is a good way to get what you want. As SS said, when it comes down to it even a low-ranked sensor can capture a decent picture, but there is much more to the story - like focus, fps and ISO for action, color depth, IQ & dynamic range for landscapes, shooting modes that can be fun AND useful, HDR & versatile bracketing, and so much more.
Did you know that the a77ii body even allows you to set a focus range limit to increase focusing speed? Say you're at a volleyball game and all the action is at 60-80 feet. Set that range and the lens won't hunt beyond it (that's a feature found in pro lenses, but now built in to the a77ii.)
You can get the a77ii manual here:

Again, I'll do some testing this weekend, and I think I'll try the EVF with my glasses on at 12fps to see how it works. I'm pretty sure the image review would be disabled at high fps, but you can easily turn it off anyway and just touch the play button to see your last shot.
Enough for now. I gotta be on the road in six hours so I'd better get some sleep. I bet I know what I'll be dreaming about, hehe.
