Nikon's new D800 SLR is a study in expectations and identity. Laid bare, the $3000 D800 is an impressive camera. But it's probably not the D800 that a lot of Nikon fans have been waiting for—what some feel they'd been virtually promised.
Here's what it's not: a tiny D4, a pint-size, light-eating dynamo. It's not even a linear progression from the D700, which was like a tiny D3. This is a whole other thing. It's more like a tiny D3x, with a gigantic all-new 36.3-megapixel full-frame sensor (FX, in Nikon speak, which you can crop down to 15.4 megapixels in DX mode).
