The flippy rotating screen is very useful -- especially if you're trying to record yourself for YouTube.

Unlike the D90, the top of the camera does not include an informational LCD. Instead, we get the rotating mode selector on the right.

The specs:

16.2 MP DX-format CMOS sensor

4 FPS continuous shooting

3.0 inch, 921,000-dot display

1920x1080 recording at up to 30 FPS

11-point AF (auto-focus) system
