What I do to be able to edit nicely on mac is convert to Apple Prores using Quicktime (before you have to install this plugin https://eww.pass.panasonic.co.jp/pro-av/support/dload/avccam_impt/agree_e.htm)
Then I conform to 25p using Cinema Tools.
Hope it helps.

I`m agree with almost all you said about the NEX7. But not that much about the noise being lower than NEX5n, I just made a quick test but NEX7 looked a bit more noisy.
Looking forward to your full review anyway.
Best.
