To sustain peak performance, even in the most demanding environmental conditions, the body, exterior, and mirror box of the D4 are comprised of strong-yet-lightweight magnesium alloy. This assures the camera's superb reliability and extra long life. Thorough measures are taken to seal and protect against invasive moisture, dust and even electromagnetic interference. A comprehensive weather and dust sealing, combined with additional Nikon engineering, further ensure integrity of the camera body
