Now that both the Nikon D800 and Nikon D800E are available, many of our readers are wondering which one to get. In this Nikon D800 vs D800E article, I will explain differences between the two cameras and talk about which camera to buy for which situation. Both cameras are identical, except for one major difference, which is why there is a price difference: the Nikon D800 has an anti-aliasing filter, while the Nikon D800E does not. In short, an anti-aliasing filter effectively removes Moiré (see below on what Moiré is), so the Nikon D800 will not have any problems with it, while the Nikon D800E cannot deal with it, so you will have to deal with it in post-processing.
A low-pass filter, also known as anti-aliasing or “blur” filter, was designed by camera manufacturers to eliminate the problem of moiré by blurring what actually reaches the sensor. While extreme details are lost in the process, the problem of moiré is completely resolved. Since most cameras are designed to be used for day-to-day photography, where moiré pattern is very common, most cameras on the market today use a low-pass / anti-aliasing filter.
