Wow! Three days after Canon announced the release of its latest-and-greatest, the EOS-1Ds Mark III DSLR, Nikon swooped in with a timely announcement of its own...for close to half the price!Nikon Strikes Back: The Highly-Anticipated D3 and D300I had to collect my jaw from the floor when I saw this. Capable of ISO 25,600?!?!?! Man, talk about blowing my concept of what's possible out of the water. And two CF memory card slots?? Nikon strikes back, indeed.View the two cameras side-by-side (Mark III and D3).
