High-ISO comparison rivalries: 1DMk4 vs D3s, 7D vs D300s

New camera-comparison action is out at Pro Photo Home, a 4-way Canon vs Nikon high ISO comparison featuring two sets of rivals, the D3s and 1D Mark IV and the D300s and 7D. The crops go from 1600 to 12800, and the RAW files are also available for download for those who want to pixel-peep-evaluate on their own. (Via the Imaging Insider newsletter)
