I have an official Nikon Newsflash in hand announcing the new D3x, dated November 30, 2008.
"Nikon is proud to announce the new 24.5 megapixel FX-format (35.9×24.0mm) D3x digital SLR…Orders for the D3x are being accepted…shipments…scheduled to begin late December…".
Learn how to optimize Photoshop for maximum speed, troubleshoot common issues, and keep your projects organized so that you can work faster than ever before!
My guess is that only a few can afford to own both. But then again, a lot of folks did own 35mm SLR plus MF film camera systems, so maybe Ann is right and folks will own both D3/D3x. At least they perfectly share lenses and peripherals.
We will need to see production pix from D3x compared against D3 before we will really know the answer to whether or not the D3x could be a "replacement" for the D3 for some photogs (perhaps the ones for whom color depth is more relevant than super-high ISO performance).
The D3 can be used right up to 6400 ISO and still produce reproduction-quality images (even up to 25,600 ISO when getting an image at all costs is paramount noise be damned!)
The D3x tops out at 1600 ISO and we have yet to see how usable that will be.
For journalists, sports photographers, travel and general shooting: the D3 would be the natural choice.
The D3x would seem to come into its own for studio and tripod-mounted location work and when enlargements above 20" x 12" is required.
Basically that means that the normal range of ISO speeds for the D3x will be 100-1600 ISO.
The "Lo1, 50 and Hi 2 up to 6400" refers to pixel-boosting using some sort of "Analog Gain" (the sort of thing that you can do on a scanner to drag detail from hopelessly under-exposed transparencies.
In comparison, the D3 offers "Lo1 = 100 and Hi 2 up to 25,600 ISO".
The Hi2 of the D3 at 25,600 ISO is noisy but still usable at a pinch with noise rather like Tri X grain with pushed development.
We have not yet been shown samples of images shot at high ISO speeds with the D3x (in fact nothing above 200 ISO) and can only guess why that is!
"I don’t understand the definition…I would find it hard to believe the 3x takes a step back behind the 3, but can’t say what’s going on… "
Gary,
The pixel elements in the D3x are much smaller than in the D3 – 5.49 microns across. That’s what is limiting the noise performance at higher ISO settings. Any ISO setting above the base setting is pushing the analog gain of the system. Past a certain point (apparently 1600 here) and the noise starts to get obtrusive.
Whether or not it’s too noisy for you depends on your needs. I shoot a ton of great images at 3200 on my 1DsMK3 Canon, and my guess is, according to some here, they would be unacceptable for "reproduction" grade images, whatever the hell that means.
Remember when we all used to shoot Agfa 1000 and T-Max3200 BECAUSE of the grain. It can actually be a good thing. Somewhere along the way the notion that great images can only be noiseless got a little too popular. There’s a reason many of our eyes are drawn to the grain and texture of film, and grainy film at that, for specific imagery.

This has been one of my pet peeves ever since the advent of digital capture. "Noiseless" capture has been held up as an absolute virtue. More often than not, I end up introducing subtle texture to the medium in order to give the image something for the eye to hold onto. Even when we were shooting Panatomic-X developed in HC-110, there was still texture.
I can stand a little noise – if the camera lets me get the shot. I did a wedding last week under horrible lighting conditions. I shot with my Nikon D300 – and an f/1.4 – 28 mm lens – I had to use ISO 1600 to get the shutter speed up to 1/60 second – hand held.
I processed the RAW images and added a bit of noise ninja – and the client loved the 8 X 12 inch prints. The noise at 1600 with my D300 is better than my D2x at ISO 400.
