The Canon EOS 1Ds Mark II has arguably the highest image quality of any currently available Digital SLR. Outstanding resolution from a rugged Digital SLR that feels great in my hand, the Canon EOS 1Ds Mark II delivers. I found not much to not like - other than the price - and the large file size required by the 16.6 megapixel images.
If 8 megapixels of resolution is enough for you and available lenses on a 1.3x FOVCF (Field of View Crop Factor) body are wide enough for you, the Canon EOS 1D Mark II is probably the right choice for you - I highly recommend it as well. And you can have two for the same price as a 1Ds Mark II.
If you can spare the high frame rate and the cash, the Canon EOS 1Ds Mark II will give you excellent high resolution images (if you do your part of course). I highly recommend it.
