Nikon D800 is just so amazing.
One of the most impressive features of the D800 is its full-frame 36.3 megapixel sensor. As of early 2012, this is highest megapixel sensor included in ANY Nikon camera (even the extreme professional models). If you want megapixel bragging rights, this is the camera for you.
In addition to this massive sensor, you also get a 51-point autofocus system that locks quickly even in very dim available light, Full High Definition 1080p video recording (with full manual control, a headphone jack for monitoring audio levels, optional external microphone and multiple frame rates), and an ISO range from 50 to 25600.
The magnesium alloy frame is heavy and solid (it weighs 9oz/120g more than the D7000 ), and the camera is somewhat sealed from both dust and moisture (just don't dunk it in a lake).
