This is the Nikon D800E, not the standard D800. While all its controls are identical, it does not have the low-pass/anti-aliasing filter that is found on the D800. This camera is useful for shooting extremely high-resolution images with optimum sharpness. However, this does come at the expense of moiré possibly showing in repetitive areas or patterns in your images. This is usually prevented by the low pass/anti-aliasing filter, but the D800E does not have the filter. While the description below is for the D800, all of the features are the same for the D800E.
The D800 offers a 51-point AF system, Nikon EXPEED 3 image processor, 3.2" rear LCD, and 91K pixel metering sensor. Among the unique features of the D800 is a 15.3MP DX-mode, allowing high-quality images when DX lenses are used. Sports shooters may also find the 25MP 1.2x crop mode useful for giving just a little more distance to their telephoto lenses. For continuous shooting, the D800 is capable of 4 fps in FX mode and 6 fps in DX mode. The button layout has gone through a slight restructuring, including the adoption of the D7000 AF mode/function control. The D800 has both CF and SDHC/XC memory card slots.
As with the D4, Nikon has included a beefed-up video mode in the D800. It records 1080p at 24/30 fps in H.264/MPEG-4 format in-camera or uncompressed 8-bit 4.2.2 footage via external recorder. The on-screen audio levels and headphone jack simplify monitoring with 20-step increments for adjusting audio levels in-camera. Full manual adjustment of exposure settings is possible, including the 1/8th-stop, power aperture mode, allowing extreme fine-tuning. For situations where external monitoring is required, the D800 allows simultaneous on-camera Live View as well.
