A few initial impressions from the past few hours..
The EVF is nice but when compared to the EVF of NEX-7, there is a clear difference. The 7's EVF much better.
The kitzoom 16-50 PZ is only tiny while not in use. Convenient to transport. That is all the positive I have about that zoom.
The 18-55 is better.
The camera (NEX-6) balances well, the controls are visible and are really useful. It does come with a hotshoe flash cover. Every fit (hotshoe cover) controls (on off switch included), LCD tilt, etc are a bit tight and work only with a bit of resistance.
The video button can be switched off although it is located out of the way.
I am yet to assign custom functions but all the useful stuff I need are already there without any customization.
I have to check out the Apps section and see if I can buy anything that would be useful.
Overall a very useful camera.
