Jmmg: The most inspirational Photographer/Artist i ever came across up to this point in my life was when I was travelling in India couple years ago I met this street photographer whose only tool is a old nikon FM2 with a 50mm 1.8 E lens plus a beat up Nikon Coolpix 4MP digital, the images which this gentleman produced blew me away and I will never forget the imagery and his creative sense of subject matter. Really, we need a 36MP camera to produce good photo? even if you are a Pro, really you need a 36MP to create your master piece? Come on, people, you really Needed it or wanted it is completely different thing...
If you want really clear prints at really large sizes, you need either medium / large format or as many MPix as you can get along with matching glass. You don't need 18 or 22 or 36 mp to produce good 8x10's, even with cropping. You DO need the horsepower to get results at large size prints, or to produce normal prints from very tight crops.
AbrasiveReducer: At last they are dumping the AA filter. No more intentionally blurring the image to make it "better".
Not so! You have to pay $300 extra or so to entice Nikon to throw it away.
For me, the video functions are nice-to-have. I do fine art and landscape work using a Mamiya 645 and p25 back. The back and camera are both wildly out of date and I can't afford to upgrade them, so welcome D800 (I use a D700 for routine shooting). I am hoping the e-version will come even remotely close to the quality of medium format ... and the D800 is going to get a whole lot more expensive when you upgrade lenses to match the resolution and sharpness of the sensor.
Anybody want to get into medium format? I can help you out;)
