Patrick Singleton at DigitalCameraInfo reviewed the Canon EOS-1D Mark II N camera. His conclusion is :

“The EOS-1D Mark II n is an excellent camera. We can easily praise the image quality and the speed and accuracy of its mechanical operations. As heavy as it is, it balances well in the hands, and the controls and dials work smoothly and quickly. Our complaints about having to combine buttons and dials to set simple controls does not detract from our overall impression that the camera is an excellent piece of equipment and the added security will likely appeal to some users.

The relatively few photographers out there who need this kind of speed and are on the fence between Canon and Nikon (without prior lens investment) should probably buy this camera. The EOS-1D Mark II n is the fastest DSLR available, at 8.5 fps, and it has twice the resolution of the runner-up, the Nikon D2Hs. The Nikon seems to have an edge in some focusing situations, and I liked aspects of its interface better, but it’s hard to argue against doubling one’s resolution. If speed is less of an issue, spending another $1000 for the Nikon D2X is a viable option, with half the resolution, apparently gorgeous image quality, and a (kind of odd) 8 fps / 6 MP mode of its own.

Overall, the EOS-1D Mark II n is an excellent tool. Its size, weight, and cost are justified not only by its speed and resolution, but by the fact that it is built to deliver those specs over the course of a long working life. “
