I'd bet the 16 BIT pipeline has something to do with it. They are going after the ultimate image quality for a 35mm dSLR.

Could be, I read somewhere the D3x board is based on the same principles as the D300.

The D3X is only 14Bit

It has a 16 BIT imaging pipeline. The final image it records is 14 BIT.

You can read about the 16 BIT image processing on page 10 of the product brochure...

I think when they moved up to 24.5 MP they just didn't have the processing power for the full framerate pushed through the 16 BIT image processor and put out as a 14 BIT file. It's like what you see with the D300. It might have something to do with pixel density. Who knows. I'm sure there is some technological reason for it though, since I don't think it's something Nikon wanted to do with either the D300 or the D3X.

To prevent any further arguments the frame rate is 1.8 in 14 bit.

That "Nikon" website is being hosted by another website. It is not the actual one I don't believe. It is someone who has set a scam up to give people viruses. I wouldn't suggest visiting that page.

I don't see this as the camera of choice for high-speed shooting. If I were using it I would just concern myself with ultimate IQ and not worry about it's machine gun capabilities. I haven't worried about the same issue with the D300, so I doubt I would be too concerned on this camera.

Then again, after spending $8K on this body one might feel cheated. The D300 was just a wee bit less expensive.

See, I guess my thinking is this:

1. It doesn't HAVE to do 5FPS in 14 bit, but it would be nice to have that option - just makes the camera that much more versatile.

2. Canon can do it, why can't Nikon a year later?

Fred,

It's a Google translation as my Japanese is terrible.

If you would prefer to read the Japanese version here you go http://www.nikon-image.com/jpn/products/camera/slr/digital/d3x/features02.htm

Regardless the frame rate drops to 1.8 in 14 bit - not just on paper, or a web-site.

Rob Galbraith has just updated his web-site to this effect - info from Nikon USA.

To repeat 1.8 at 14 bit.

Near the bottom of the page, on the following link, are the buffer rates - http://translate.google.co.uk/translate?u=http%3A%2F%2Fwww.nikon-image.com%2Fjpn%2Fproducts%2Fcamera%2Fslr%2Fdigital%2Fd3x%2Fspec.htm&sl=ja&tl=en&hl=en&ie=UTF-8

You're right, but I don't like Nikon hiding this.
This kind of things make you worrying if there're more things "Nikon "hide" with this cam.

Could it be when it is creating the 130 Mb files?? I guess that would slow down most cameras?

p.2 #10 · D3x framerate?

Rob Galbraith updated his preview adding info on buffer and framerate:

FX Format, Lossless Compressed 14 bit NEF (1.8 fps): 28 frames
FX Format, Lossless Compressed 12 bit NEF (5 fps): 24 frames
FX Format, JPEG Fine (5 fps): 44 frames
DX Format, Lossless Compressed 14 bit NEF (2.6 fps): 52 frames
DX Format, Lossless Compressed 12 bit NEF (7 fps): 32 frames
DX Format, JPEG Fine (7 fps): 76 frames

The number of frames in NEF 14bit is higher than D3's without buffer upgrade, but at 1.8/2.6 fps instead of 9/11 fps it is understandable.
