Totally invalid, meaningless test.

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 test is invalid and as they have the same sensor, the result should not be that drastically different. |

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

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. |

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. -- -- r.p.e.35mm user resource: http://www.aliasimages.com/rpe35mmur.htm -- r.p.d.slr-systems: http://www.aliasimages.com/rpdslrsysur.htm -- [SI] gallery & rulz: http://www.pbase.com/shootin -- e-meil: Remove FreeLunch. |
