There are two analysis by Rob Galbraith which may answer most of our queries of Eos-1D Mark lll autofocus performance and the performance of the Nikon D3.
An analysis of EOS-1D Mark III autofocus performance Tuesday, June 19, 2007 | by Rob Galbraith
In our April 22, 2007 first look at the Canon EOS-1D Mark III, we described the camera’s autofocus as being blazingly fast at acquiring initial focus. So fast that covering women’s volleyball over several days was pure joy, thanks to an incredibly responsive autofocus system in the preproduction body on loan from Canon. We also found its autofocus to be quicker off the line in dim light than any camera we’d used before.

The Nikon D3 from ISO 200 to 25600 Thursday, November 15, 2007

Nikon has taken a grassroots approach to marketing their upcoming D3 digital SLR, putting it in the hands of professional photographers far and wide in the months leading up to its expected late-November release.

Such is Nikon‘s confidence in their first full-frame offering.
We’ve gathered files from three such photographers – Tony Bock, Nick Didlick and David Einsel – as well as photographer/author Peter K. Burian. From ISO 200 to 25600, here are full-resolution examples of what Nikon‘s new flagship is capable of.
