You can finally download some D800 NEF images from http://narod.ru/disk/40067882002/1.zip.html This is a Russian site and you simply have to fill-in the sign-in number shown near the bottom of the page to go to the next (download) page. There are a number of the same image taken at various speeds. Takes a couple of hours to download with a very good connection speed; so don't bother unless you have such a connection.
EDIT: I don't think this link works anymore; at least, they've changed their page and, since I can't read Cyrillic or whatever they are, I can't figure out how to enter the site now. Sorry!

>I get no reply from that website, using either link. Perhaps it is overloaded...?<
Not sure. I checked my link after I posted, and I've just checked it again now. Both times it has worked fine.
In any event, I have downloaded the zipped folder and examined the contents which consist of 8 NEF files shot with a D800 and 50mm f/1.8G lens at f/2.8 aperture. Quality is 14 bit lossless compressed. ISO varies using a setting of 400, 800, 1600, 3200, 6400, 12800 and 25600 for an image of flowers, with the 8th image of a chandelier at ISO 6400.
I think Rob and I must be looking at different images, because from what I see the D800 images are far from what I consider to be beautifully sharp.
Where is a base ISO (100?) image? This is the setting at which the D800 should shine. I have to presume that ISO 400 was chosen as the lowest setting to begin the sequence because the shot was being hand held.
By ISO 800 noise is for me quite pronounced, about the same as the D300 at ISO 800 from what I can remember (I virtually never shot above base ISO with the D300). Perhaps downsampling to make a direct comparison fair will change things significantly.
I've not shot a D700, but given that it is meant to perform as well at high ISO as the D3 it canabalised, I would be very surprised if the D800 performance is equal to it, though clearly I'm guessing here. Again, downsampling will make a direct comparison fair.
At higher ISO settings things only get worse, which I dare say is true of all cameras. At ISO 6400, the chandelier image is very poor in my opinion. I didn't look at the flower image at that ISO, but why would it be any different?
It is possible that the NEFs, which I am surprised to say I was able to open in Capture NX2, were shot without sharpening applied in camera. However, applying sharpening to the image shot at ISO 400 (highest quality example image provided) only improved the image, it certainly did not deliver the quality I currently am used to seeing.
For me, the jury is still out on just how good the D800 potentially can be. To date I remain unimpressed.
EDIT: For those interested, try comparing one of the images from here to the D800 images in terms of sharpness.

"Here is a better shot to compare to the Leica link'.
Thanks God (and Christopher), that looks more like what I was expecting! This can compete with the Leica pictures in terms of sharpness (not in terms of art direction and make-up though). It is taken with the D800E I see in Bridge.
These are the NEF files I used to determine read noise and Photographic Dynamic Range (PDR). I made a post Nikon D800 Read Noise Measured and Compared last Wednesday that went unnoticed. The results are impressive. For further info see various articles listed at the top of my site. Please respond in that thread if you have questions/comments about those results.
Regarding sharpness. I don't think these NEFs are representative of what the D800 can do.
Well, I've played with these images for a while now and I think that my D700 is holding up pretty well. I don't have the 50mm f/1.8G lens with which these were taken; but, I do have a 50mm f/1.4G that is probably just as good (maybe slightly better). My shots seem to compare favorably with the D800's in images blown up to 17 x 24 nominal size prints, which is as large as I can now print (with an Epson 3880), so I'm not inclined to spring for the D800 in the near future. Of course, If i didn't have a D700, I would go for the D800.
It is fair to say that I have definitely not done any extended testing at low levels, extended ISO's, etc. At any rate, it's nice to see Nikon pushing the limits further.
