Together with the D5100, Nikon will also introduce a revolutionary new brand called NIKKORNER which will include products from the Imaging and Sports Optics divisions. In the Imaging division, Nikon will be announcing a new lens that can take pictures around corners and protect photojournalists when working in dangerous areas. The lens will be available also in camouflage pattern/colors.
