Nikon D800

The Nikon D800 is a 36.3-megapixel professional-grade full-frame digital single-lens reflex camera produced by Nikon Corporation. It was given a Gold Award by Digital Photography Review.
It was officially announced on February 7, 2012 and went on sale in late March 2012 for the suggested retail price of $2999.95 in the U.S., £2399 in the UK, and €2892 in the Eurozone. Shortly after the camera went on sale, Nikon's UK subsidiary increased the price of the D800 in that market by £200 to £2599, saying that the original price was due to an "internal systems error". However, Nikon honored the original price for all pre-orders placed before March 24, and added that no price changes would be made in other markets.
The successor is the Nikon D810 – announced June 26, 2014.

At the time of its release, the Nikon D800 became the Dxomark image sensor leader, replacing the Nikon D4 in the top position.
D800E.
The D800E is a specialized version which uses a new optical anti-aliasing filter with no low-pass filter effect (no blurring) to obtain the sharpest images possible. Nikon claims that possible aliasing effects (moiré) can be lessened by software-processing in camera or external programs like Nikon's Capture NX2.
Reviewers have pointed out that although increased moiré is difficult to remove in post-processing, it is relatively easy to combat while photo-taking (such as by changing the angle, aperture or position). Furthermore, moire is rarely found in photos (besides man-made, repeated patterns such as in architecture). The lack of low-pass filter brings about a small improvement in optical resolution in the 800E, especially in portraits with larger apertures, where diffraction is not an issue. Even minimal diffraction, negates the advantage of the 800E 
Mislabelled D800 as D800E fraud.
Nikon has advised that there are mislabelled Nikon D800E in circulation that are actually the D800 model with the front cover replaced so as to appear like a D800E. A D800 modified to appear to be a D800E is not covered under Nikon warranty. Nikon advises users to "please take all necessary precautions to ensure the authenticity of a camera before purchasing one".
To detect fake models the user has to display an image captured with the camera in the camera's monitor. The name of the camera used to capture the image will be displayed at the top right corner of the display when the "overview" display option is enabled in full-frame playback mode. If the correct model number is displayed, it is authentic.
