Totally invalid, meaningless test.

Amazing! Images taken with a camera that has not even been released
yet! (And it is not scheduled for release for another month.)

Maybe you would like to see the terrible color balance, noise, and
purple fringing in my test shots with the Canon 1DS Mark III? Or the
Hasselblad 1D-82? Or any other non-existent camera.

The pixels are 1/3 smaller than the D50. No surprise if there is more
noticeable noise
at 1600 ISO.

I thought the D80 shot is brighter and indeed, it's shot at 1/20sec and
the A100 shot is 1/40sec. The test is invalid and as they have the same
sensor, the result should not be that drastically different.

Pre-production samples have been in the hands of select people for a
while. Where do you think sample photos for Nikon brochures, and online
tests get their info?


And you honestly think that these photographs were produced by some of
these "select people?"

If these photographs were taken with a D80, lets see some proof.

How much more do you need?

And yes -- they *are* JPGs, not BMPs as was suggested earlier.

Enjoy,

I don't know why you can't read exif - seems to be intact. Of course
there is no "proof" it isn't forged.
The D80 / a100 comparisons aren't particularly interesting due to the
large difference in exposure, and unless you can read japanese on the
other link, no idea what NR settings were used in camera etc.

Exactly. Anyone can change EXIF data.

1) There are no D80s in the hands of the general public.

2) None of the credible reviewers seem to have a D80 yet.

3) Anyone publishing pictures like that could pretty well be guaranteed
to never be allowed near a preview copy of a new Nikon again.

4) The pictures have been processed, as noted by others, so even if
they were taken with a D80 we have no idea what was done to them in the
interim or what the settings were.

Without further evidence that these photographs are genuine and
untampered with they should be simply dismissed out of hand.

I DL'd the photo as shown and loaded into PS Elements. All EXIF fields
were blank. That may be a shortcoming of PS Elements, OTOH, I DL files
from elsewhere and the EXIF are intact. That was not the case with this
image at the link provided.
