John, are you thinking about buying your "nex" camera?
Heck dunno Wylie .... nothing in PhotoKina for me ... perhaps the Pany 100-300 or the Fuji EX100
The NEX is really beautiful it stands out compared to Oly and Pany from a stand point of Aesthetic design in particular the lenses.
Oly m43 lenses look a little Retro and only Ok while Panasonic lenses have a "bland" look with awful screen printed legends in an awful font the grips and body show little imagination .... like work from a 1st year Industrial design student.
There I've said it and that said the optics of Panasonic are excellent with the OIS but never win a design award.
Problem with the NEX is it may sow seeds of dissatisfaction with mu m43 gear (And I have a lot of it) if I start to Pixel peep NEX / versus M43.
