Digital Outback Photo have published a very interesting article today comparing the depth of field that can be obtained by the Nikon D2X and Canon EOS 1Ds Mk II DSLR cameras.

“If you are shooting where significant depth of field is required, the D2X will better serve your needs, producing more sharp pixels overall than the 1DsMII. Or, the D2X will be able to shoot at a higher shutter speed while obtaining the same DOF. When the wind is blowing, details like leaves or flowers can be obliterated by a too-low shutter speed. When it’s dusk, you may not be able to stop down to get DOF and still get a fast-enough shutter speed. You can raise the ISO on the 1DsMII, but that degrades picture quality. And in these examples, even f16 was not enough to make up for the disadvantage. Going beyond f16 on either camera seriously degrades overall image sharpness and contrast, though in this case perhaps it would be an improvement for the 1DsMII.”
