Quote from TeddyBearEOS 1D Mark III seems to be the camera I am looking for. Thanks again, hessi
EOS 1DMIII (not 1Ds) is the perfect camera then, you have already given the limiting requirement of 10fps (e.g the Nikon equivalent D2Hs is "only" 8fps) . The 1D MIII is more than capable of what you are probably searching for.
Although, given the high price of around 5,500$ (only converted price from current €-worth), you will have to spend at least another 3-4k for appropriate lenses (Unless you already own some) - Depending on the focal length range you're trying to cover.
