Personally I am absolutely disappointed! The D700 had been an more economic, slightly downgraded, much more compact version of Nikons pro flagship camera, but the D800 follows a completely different way. Instead of using the same sensor as the D4, which offers more than sufficient resolution, Nikon decided to build a "resolution only" camera that would hardly appeal to anybody else than landscape, wedding and portrait fotographers.
I don't need 36 megapixels (I have no wall in my flat which is large enough to really have advantages of this gigantic resolution), my computer hardware can't handle NEF files of 76.5MB, but for action photography I need up to 8f/sec! And then there is of course the lens problem, hardly any lens except of Nikons top range lenses will be able to make use of this sensor!
Maybe I should look for one of the last D700 bodies out there and store it as a backup for future use?
Sorry Nikon, no money from me for a D800!
I am sure many owners will be disappointed because of unsharp pictures, when they try to use the 624mm tele setting in combination with those typicall stretched out arms! :-)
A 24 or 22mm lower end makes more sense for creative photography, than this crazy tele range!
