I was one of the lucky ones to get on the first batch, and man oh man, what a camera, Love it!
At first the menu is a nightmare for a guy that shot with Nikon and Canon Cameras for over 27 years.
I love everything about it, once I got use to the menu, it's a breeze, I customized to my use and I just love it. The way I customize the FN button, which is one of the things I love the most, I make all the necessary changes I need it while shooting and without taking my eyes from my subject or my EVF.
I shoot at hight ISO's, which is a must for me without worrying about, I know my files will be great, I go up to ISO 6400 without excitation and the result is a mind blowing.
The only thing I would complain about it, but is easy to fix with a firmware/update is the AF point (the little square), Sony, you Need to Change the Colour of it, it's a nightmare, we can't see this thing depending on the light condition. Please!!!
All the rest is a wonder all I hope for and dream of.
