I own a Nikon D90 and want a better camera so my photos look better. I was thinking of getting the Nikon D800 or the D4. The D800 I'm sure will look better because of the higher megapixels which means its a professional camera. All my photos I upload to face book look blurry and blocky. Also The D800 uses the SD cards which my D90 does but also has a CF card slot, which I assume holds better quality photos since its bigger? I'd like to stay with Nikon because I have the 18-200 lens that came with my D90. But If I have to go to another brand like canon or hasselblad to get better pics then I have to.
