Virtual Horizon

Nikon D7000 setup menu Virtual HorizonExplanation: A display like a virtual horizon in the cockpit of an airplane displays if the D7000 is horizontally aligned or not. It does not visualize if the lens is pointing up or down.

Tips: For hand held shooting it is not usable, you cannot look through the viewfinder and on the monitor at the same time.
For adjusting the camera on a tripod you may use this if you like.
