I bought a PEN F as a carry around camera, and while nice, the specter of knowing that chip is small haunts me. I'm thinking about trading it for an A7. For those of you so equipped, I need to relate AF speed/accuracy to something I know. How does the A7 compare to an A6000 in AF, and maybe to an A7ii? I have both of those, so comparisons can be made that I'd understand. I LOVED the NEX-6, but at some point the AF was just not there in comparison to the A6000, and it had to go. If the A7 is in that league, I'd skip an A7. We're taking an extended vacation in December and I don't want to take a lot go gear. The PEN F fit that profile nicely, being such a tiny kit, but as of now I'd take my A6300 (or A6000) and a couple of lenses instead. I don't care about video.
