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. 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.
