A review of the Canon EOS-1Ds Mark II digital camera is available at dpreview.

Here is an abbreviated version of the review conclusion:
“[…] The EOS-1Ds Mark II delivers a level of detail unmatched by any other current digital SLR
Performance is another area which impresses […]. The EOS-1Ds Mark II’s problem however is its big price tag.
However for the professional (especially if they already own Canon lenses) to whom price is not a deciding factor and who wants the ultimate in high resolution, a full frame sensor, professional features, build quality, speed and reliability the choice is simple.
Highly recommended.”
