Well, the only picture among these that required quick focusing is the one of the Japanese tourists at the Lincoln Memorial, and that was shot with the 24/1.8, which is autofocus. And it was plenty quick. Otherwise, I use the EVF most of the time, and I find it's pretty easy to focus with the peaking feature on. I put it on the lowest setting, with white as the highlight color, and don't have many issues. It's not perfect but it's my default setting for a reason.
But I do use the screen a fair amount, more than I expected I would. With its ability to fold out, it's great for low angles or situations where discretion is warranted. The shutter is really quiet also, so that helps.
Otherwise, I like the way the NEX-7 handles, especially with the legacy glass. It's replaced my 7D/17-55 as my travel camera, and I find myself using it in commercial applications more and more. The video is good too; I like that I can work with ISO values instead of gain, and control shutter and aperture directly in a manner that I'm used to (as a stills guy). I'll be shooting commercial projects with it before the year is out.
