I got up early to shoot the sunrise and some birds with my new Sony NEX-6. This is the first camera I've had that utilizes an electronic viewfinder.
Focusing has proven to be easy, even in the dark. That's a plus.
However, every time I take a photo, the viewfinder blacks out. There's a noticeable lag before it comes back on. That blackout makes it really hard to follow birds with a long zoom.
Guess you better compose each shot right the first time ...
