The D800E is a specialized product designed with one thing in mind, pure definition. The D800E incorporates an optical low pass filter (OLPF) without anti-aliasing properties to facilitate the sharpest images possible and is a great option for RAW shooters who are in a position to control light, distance and their subject to the degree where they can mitigate the risk of moiré and any false color.1-Year Limited Warranty.
