Does anyone know if the focusing system on the original Canon 1D mk 1 is the same as the 1D MK 3 ?
Has Canon changed anything on the 1D series from the original 1D to the current 1D's

They have the same number of focus points with the same distribution however every newer generation of the 1D had more cross type sensors. I also wonder if the have the special f2.8 sensor with diagonal axis as well on the 1D3? As for the programming and processing that goes on I would assume it has been tweaked but I am a bit unsure.

One thing the Mk I (and II) offered that the III lost is manual selection of any of the 45 AF points. However, the Mk III
has more cross-type sensors than the earlier versions.
The Mk III focuses in lower light levels than the earlier bodies could manage.
The focusing algorithms have changed with each model, with plenty of raging arguments about what works and what doesn't.
The 1D Mk I AF was (is) excellent for the resolution at 4MP and the 8 fps speed. 10 or 21 MP can show minor misfocus
that you wouldn't spot in the 1D 4 MP files, but that's not to say that there was anything lacking in the AF performance.
