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.
4 frames per second in continuous FX mode or 5:4 crop mode. 5 frames per second in continuous 1.2× crop mode or DX (APS-C) mode. With the optional MB-D12 battery grip, fitted with either the EN-EL18 battery pack of the D4 or AA batteries, continuous shooting at 6 frames per second in DX mode is supported.
Buffer size for 17 RAW or 56 JPEG with maximum quality.
The Nikon D800 achieved a new 'king' result in the DxO Labs/DxOMark sensor rating by toppling the D4 by 4 points, even though the D800 is cheaper, being about half the D4 price (better quality-to-price ratio).
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 whilst increased moire is difficult to resolve 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). Hence, most recommend the D800E, as the lack of low pass filter brings about a noticeable improvement in optical resolution.
