The designers at Nauticam are themselves underwater photographers, so they understand that time is very precious in the deep blue. The Nauticam housing is a natural extension of the camera. Every control is well thought-out, every button, lever and switch considered not in terms of what is easier for the designer, but what is best for the photographer. The D500 housing body is machined from solid aircraft-grade aluminum, then hard-anodized to make it impervious to salt water and give it an impressive 100-meter depth rating.
