These new super-telephoto lenses are equipped with a vibration reduction (VR) function. Nikon’s VR II system minimizes image blur caused by camera shake, offering a shutter speed up to the equivalent of four stops faster.* The newly added Tripod mode reduces vibration that may occur at shutter release when shooting with a super-telephoto lens attached to a tripod. Another big advantage of Nikon’s VR function is that it gives photographers the option of a natural viewfinder image even during VR operation.

Nikon patents full-color RGB sensor

Here's an interesting patent from Japan's Nikon Corp.

Color separation device of solid-state image sensor

Abstract
A microlens condenses incident light to an opening. Light passed through the opening reaches a first dichroic mirror. The first dichroic mirror passes blue light and reflects green and red light. Only the blue light is incident on a first light receiving surface. The first dichroic mirror leads the green and red light to a second dichroic mirror. The second dichroic mirror passes the green light and reflects the red light. Only the green light is incident on a second light receiving surface. The second dichroic mirror leads the red light to a third dichroic mirror. The third dichroic mirror reflects the red light. Therefore, the red light is incident on a third light receiving surface.
