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

The superior functioning of the newly developed
optical system ensures flawless synchronization with Nikon’s digital
SLRs. The new optical design features three ED (Extra-low Dispersion)
glass elements that minimize chromatic aberration, producing
consistently high-quality images. Nano Crystal Coat, extra-low
refractive index coating, virtually eliminates internal lens element
reflections across a wide range of wavelengths, and is particularly
effective in reducing ghosting and flare. A meniscus protective glass
element also minimizes the ghosting that occur when light reflected
from a digital camera’s image sensor is in turn reflected off an
ordinary flat protective glass element.

Nikon’s
exclusive Silent Wave Motor (SWM) provides fast autofocus with superior
accuracy and ultra-quiet operation. All lenses feature nine-blade
rounded diaphragms that ensure a more natural look for parts of a scene
intended to be out of focus. The minimum focus distances are 2.9 m/9.5
ft. (400mm f/2.8G), 4.0 m/13.1 ft. (500mm f/4G) and 5.0 m/16.4 ft.
(600mm f/4G) respectively (at AF) — much shorter than their
predecessors.







Ergonomically arranged switches and buttons
enable easy access and comfortable operation even during handheld
shooting. The Focus Preset function instantly recalls a focal point
preset with a simple pushbutton operation; the Focus Limiter switch
restricts AF-servo movement to a controlled shooting distance range;
the AF-L switch makes it possible to lock focus from the lens; and
AF-ON engages autofocus from the lens.



The new A/M focus mode allows instant switching
from autofocus to manual focus, even during AF servo operation, and
offers a major improvement over conventional M/A modes by significantly
reducing the possibility of unintentional switching from Auto to Manual.



By employing magnesium die-cast in the lens body
construction, we achieved considerable weight savings without
sacrificing rugged field-proven construction resistant to both dust and
water.



With their unprecedented image quality,
responsiveness and versatility, these new NIKKORs are certain to set a
new benchmark for super-telephoto lenses.

Nikon D3 Announced…

"It’s a brick, a frickin’ brick," said an obviously agitated Tommy Hogan, professional photographer.

"Yes, it’s a brick," admitted Nikon President, CEO and COO Michio Kariya. "However, research showed us that we were rapidly losing market share in the professional realm to Canon. Here at Nikon, we’re not so prideful that we refuse to admit when we’re wrong. If photographers want a camera like Canon offers, we’ll build a camera like Canon offers. In this case, the brick was the closest we could come to achieving the ergonomics found in Canon’s 5D."

Jerry Yamamoto, Nikon’s Chief Designer, had a different take. "Today, it seems that more and more of our customers are using their gear to photograph brick walls. Nikon cameras have always been about transcending the equipment—the camera becoming part of your environment. It’s easier to think artistically when you aren’t using a tool that seems out of place. The brick design of the D3 is part of a move toward better fusion with the photographer’s surroundings."

But the brick design isn’t the only feature of the D3 that has left potential customers scratching their heads. The D3 will be Nikon’s first digital SLR that prevents the user from changing lenses. "I don’t get it," Nikon enthusiast Rory Bjornlett said. "How is that supposed to be a ‘feature’?" Kariya had the answer.

"By shipping the D3 with the lens welded to the body, we’ve eliminated the sensor dust problem. In fact, we guarantee that you will never get dust on the sensor for the life of the camera. And now, you can order exactly the camera you want. Your D3 can be customized with a wide assortment of Nikon and even third-party lenses. Just tell us what you want, and we’ll weld it to the camera and ship it to your door within a couple of weeks."

When asked for clarification about third-party lens options, Kariya pointed out that companies like Sigma and Tokina fill niches that Nikon doesn’t have the time to bother with. "A few of our more demanding customers have been asking for a fast AF-S prime in the 30-35mm focal range. But this doesn’t fit into our long-term plans. There are still three or four more consumer zooms in the 18-70mm focal range that we need to get to market before we can worry about a prime lens that only a few professionals and enthusiasts will ever use. Since Sigma offers such a lens now, we’ve decided to go ahead and offer it as a customization option for D3 customers. Maybe that will shut them up. This is off the record, right?"

Photographer and writer Rockwell Kenneth, an attendee at Nikon Corporation’s D3 media event, was distressed to learn that all D3 lenses will only allow for manual focusing. "Getting rid of autofocus seems like a serious step backward. I can understand the less-is-more mentality, but this? Looks like I’m going to have to stock up on more D40s and 18-200 VRs. It’s all you really need, anyway."

Nikon designer Jack Kogaku explained Nikon’s reasoning behind removing autofocus. "We’re trying to build a camera that can compete with the competition, and it’s tough. We had our work cut out for us. Our moment of epiphany came when we received a shipment of Canon EOS 1D Mark IIIs. We quickly realized that manually focusing the D3 was just as fast as autofocusing the Mark III, and about 277% more accurate. Out with the old and in with the new, ya’ know? Manual focus is the new black!"

Other improvements include better digital noise performance. "We’ve heard the complaints about the noise of Nikon cameras versus their Canon counterparts for a couple of years now," Kogaku said. "We’ve done our very best with the D40, D80, and D200 to provide better noise performance, and while I feel we succeeded, the public apparently disagrees. For this reason, we’ve completely removed the mirror from the D3. No mirror slap means no noise whatsoever. If you thought the D40 or D80 had low noise, wait ’til you hear this! The silence is deafening."

The removal of the mirror from the D3 means that users must frame the image using one of the two holes in the brick on either side of the lens. This design move by Nikon has also ignited debate over whether the D3 is an SLR at all.

"That’s not an SLR, it’s a rangefinder," insisted one indignant media correspondent who had flown in from the United States. But a source within Nikon who asked not to be named due to his corporate espionage activities on behalf of Leica disagreed passionately: "If that’s a rangefinder, then my name isn’t Wolfhausen!"

Missing from the announcement was Nikon’s rumored full-frame digital SLR. "Foo-frame? What dat?" asked Nikon spokesman George Takiyama when the rumor was brought up. Several reporters tried to explain the term to Takiyama, at which point he said, "No Engleesh. Speaky Japanese." When a Japanese reporter pressed the issue in Takiyama’s native language, he responded in English, "Oh, you never need do dat! No foo-frame ’cause no need foo-frame! We defy laws of pheesics. Canon no can do, so dey need foo-frame."

The D3 comes equipped with a convenient carry handle and hundreds of lens customization options. The camera will begin shipping next week, though widespread availability isn’t expected until the end of next year. The estimated retail price of a D3 with a welded, manual focus Nikkor 17-55mm f/2.8 is $4995.

Is Nikon to release an 18-megapixel D3

I have no idea how
true this is but things may turn out just nice if they are going to release it
soon as to compete with Canon’s 10 fps blazing Mark III Sniper ! If the
specification and price is as what is mentioned, this honey will, theoretically,
outperform the Mark III. A FF (Full Frame) dSLR with the option of 1.5x crop
factor when shooting at high fps makes thing 100% sweeter!

 

7 March 2007 – It seems that diehard Nikon fans are
still holding out for a full-frame DSLR, despite the company's emphasis on its
commitment to a smaller sensor size.

Now one website has details of a rumored D3, a successor to the D2X, that was
apparently unveiled to sales representatives in California.

A man called Jim Seaholm says that the specifications include a full-frame
sensor, although for high speed shooting a 1.5x crop factor will be applied.

Most controversially of all, the report says that it will have 18.7MP of
resolution.

The price for this monster? $8000, around the same amount as Canon's 1Ds Mark
II.

In addition, the mole reported that two lenses are in the pipeline, one a 50mm
1.2G AF-S lens, and the other a 24-120 2.8G AF-S.

Although this may indeed turn out to be "vaporware", one thing is for
certain, and that's that the top two camera makers are predicted to add
considerable pixels to their sensors in the next iteration of professional
cameras – Canon's next pro camera is rumored to have 22MP of resolution,
bringing it up to medium-format quality.
