I can tell you with confidence in years of use - dark settings and fast action tracking, that the AF in the EOS1V & 3 + L lenses worked instantaneously and uneventfully. The manual focus override on the lenses are quite useful too. The bodies will not need an upgrade and the focus motors are in the lenses. For that matter, there are no dslrs that have ECF.

I have an EOS 5 and the ECF didn't work for me (I wear glasses). Supposedly the more times you perform the calibration the better it gets - I found more calibrations made it worse.
I was an opponent of AF for yearsbut after using 3Nikondigitals,I wouldn't want to be without it anymore.I ran several comparison testsand now consider MF as being pure serendipity compared to AFYou just can't compete with it.
