Nikon's answer to the Canon 5D Mark II and now-competitor to the 5d Mark III, the D800 replaces the aging D700 as Nikon's cheapest full-frame camera (half the D4's $6000). Crucially, the D800 adds 1080p video recording and ups the resolution to 36.3 megapixels, handily eclipsing the more expensive D3X. Test images reveal that the D800 is better than the D700 at high ISOs and obviously captures more detail and a greater dynamic range than anything else on the DSLR market. It also hits the scale at nearly 200 grams lighter. The D800's frame rate is a paltry 4fps without a grip, however, so for sports you may want to look elsewhere.
