When does the poll end? My Nex7 still isn't here.
I haven't handled every camera on the list either. But before I bought the a77 I really done a lot of homework. I read reviews, looked at DXO marks and dug up as much info as I could. As far as third party glass on the NEX7 if I could afford three Leica lenses I would own an M9.lol
To be honest your better off using the glass designed for the job.
I think I have used my Voigtlander 28 on my NEX5n once.
