"Its raison d'être is its 10fps, and I don't need that enough to pay the premium price for it. That said, if I were a Canon shooter I'd have my order in. But there's a few things that are making Nikonians sweat. First of all, Nikonian sports shooters, whichever of them are left, should be in a state of mild panic. Canon was already lapping Nikon in sports, and now they're in a whole different race. In fact, I'm scratching my head a bit as to why they chose to update their sports camera, when their true flagship, high-resolution-but slower 1DS line is much longer in the tooth, and not trouncing Nikon in its market as severely. But the paperwork on this thing promises even better low-light image quality than the 5D, the current champ. That's a huge thing for me. I have to compete with other photographers. If someone has this and can shoot at four times the shutter speeds I can because of noise performance, they have a pretty big advantage. Nikon has done amazing things with sensors at the low-end -- the D40 performance is class-leading -- but they end up having to polish the same mediocre Sony sensors throughout their line."Some interesting thoughts on the new Canon 1D Mark III from a photographer who shooks Nikon. His comments about the low-light performance improvements are particularly interesting. Worth a read!
