I had not yet the pleasure of playing with the NEX7 but am the proud owner of a Nex 5N complete with EVF and the AF A mount adapter. The central placing of the external EVF is more natural to me since I am more used to SLRs compared to range finders. The evf and the flash being mutually exclusive (since they install on the same hotshoe) bothered me at first but it actually makes sense that if it is dark enough to need flash glare on the live view screen is not a problem. The Nex5 can be regarded as a customizable modular system where the Nex6 and Nex7 more of a one piece integrated solution. It wouldn't be so bad if Sony can release a 24MP variant of the Nex5.
