Haven't checked this specification for a long time, but with the
EOS-1(n), there was a limit of f2.8 for the AF-sensor, being
functional with both vertical and horizontal lines.
On the PhotoKina, the Canon guys looked at me as if they saw water
burning, when I mentioned this in the context of the new 70-200/4.0
IS....as if there never was such a limit, for more than one
generation....
Yet I don't even recall any big boasting of this limit being
nullified with any of the later EOS-1 series....
I do recall vaguely that the medium grade models suffered less from
this, but only by comprimising low-light performance....the center
sensor of the EOS-1 was much better in that context)

(still waiting for a 200mm/f2.8 IS, or even a 200mm/f1.8 IS
DO....just that the darn thing fits upright in my LowePro backpack,
like my 200/2.8 currently does, unlike all the IS-zooms in that
range)
