[font color=\'#000000\']The 1D image compares favorably with the 10D because of a less severe AA filter. The tradeoff is potentially more serious moire problems in selected situations. While high ISO performance with the 1D is very good, long exposures (5 seconds+) will be better with the 10D.
Other advantages of the 1D aside from what's already been mentioned (build, fps, focus speed):
- true spot metering
- somewhat better dynamic range
- better auto WB
- high speed flash sync
- lower crop factor (1.3x vs 1.6x) can be important if you shoot wide
