The Canon EOS-1D Mark III Digital SLR is the world's fastest digital SLR camera says Canon. At 10 frames per second, the 10.1MP EOS-1D Mark III digital SLR can fire motor-driven bursts of 110 Large JPEGs or 30 RAW files. Canon achieves this performance with the new Dual DIGIC III image processor engine. The all-new 10.1 megapixel, APS-H size CMOS sensor gives you a ISO range of 100 to 3200 with extensions to ISO 50 and a highly usable ISO 6400.
