It's not just performance, it's total performance. The EOS-1D.
If you need speed, look no further: capable of 8 frames per second, for up to 21 consecutive shots, the EOS-1D is one of Canon's fastest digital SLR cameras. The EOS-1D has a 4.1 MP CCD (1.3x conversion factor) for high-performance imaging, manual settings for color space, white balance and tone curves, seamless compatibility with Canon's range of lenses and Speedlites, entirely new driver software for the PC and Mac with powerful new tools for image control and camera customization, and a host of other custom features. A magnesium alloy body and chassis, extensive moisture and dust resistance, combined with the handling and build quality of the EOS-1v make the EOS-1D a sports and action photographer's dream come true.
