Thank you Dallas.
The camera is very nice to handle, lightweight and with a good grip .
As I walk all day during my photo sessions it is a joy.
Image quality is similar to my D5, but I suspect not in low light photography. I have to confirm that.
Three things I don´t like so far:
1- Batteries: I have to manage it more carefully and always carry a spare in my pocket. With My D5 and D4s I don´t have to worry about it. One battery fully charged in those cameras lasts almost one week for me, shooting everyday.
2- I like to use manual focus lenses and I miss the white/green dot focus confirmation when using these lenses. The peaking highlights sucks for my kind of photography (street and landscape). Maybe it is the best for macro work, but I don´t do that. That´s the main disadvantage of this camera for me.
3- The EVF has to be turned on every time you need it. You can set it to automatically do so when you place the camera in your eyes, but there is an annoying delay. You can train yourself to press the shutter release while bringing the camera to your eyes or leave the EVF always on, which will drain more power.
I'm still waiting to purchase my first Z lens to see how the combo works. I'm planning to buy the 14-30mm f/4 zoom and the Noct.
Nikon said they will be released in spring, but I'm not sure in what year!
