Thanks, JT! Sony has many years of experience with peaking on their pro video cameras, and have, with great success, brought this on to their NEX. I don't know too much about the other NEX models, but the NEX-7 is a sheer wolf in sheepskin. I sold my M9 recently; bought a second NEX-7 instead! So, with some training I prefer my manual Leica lenses to any autofocus . . provided I have the peaking function intact! (I preordered the M, but dropped it after hands-on, it's lightyears after the NEX, operation wise)
