Nikon AF-S 400mm f/2.8G ED VR 500mm 600mm f/4G ED VR

Three new professional super-telephoto NIKKOR lenses featuring VR II

Tokyo – Nikon Corporation is pleased to announce the introduction of three new AF-S super-telephoto NIKKOR lenses — the AF-S NIKKOR 400mm f/2.8G ED VR, AF-S NIKKOR 500mm f/4G ED VR, and AF-S NIKKOR 600mm f/4G ED VR — to further strengthen its super-telephoto lens lineup.

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.

Sony/Alpha Full Frame Lenses: 300mm f/4 and 600mm f/4 or200mm f/2.8? (Photo)

Sony has also made available, via hard-to-find areas of international websites, images of the next round of Sony SAL lenses to hit the market. Details of the specifications have been leaked, probably from the June 2007 meetings in Japan. All the new lenses are full-frame, confirming the rumours that the ‘A-500′ due in 2008 will be a full-frame or 1.1X model

The 400mm f/4.5 and 600mm f/4 Sony SAL G (D) apochromatic telephotos were known to be in the pipeline from the start. They are revised versions of the classic Minolta G glass, and are presumed to use SSM sonic motor focusing because it was known that Konica Minolta already planned to incorporate SSM into these long lenses. However the prototypes shown and photographed may be a 300mm f/4 and 600mm f/4, or even a 200mm f/2.8 (looking at the size of the AF hold button on the smaller lens). The relative size of the mount, the tripod collar handgrip and the rear filter slot indicate that the larger lens is the 600mm. Statements that the smaller one is a 400mm f/4 seem very unlikely judging from the mount size and the tripod collar. It looks most like a new 300mm f/4 but could be a focal length we have not seen before, like 240mm or 280mm, or an aperture like f/3.5 instead of f/4.
