EOS magazine was wrong. AF on the 20D shuts down at
apertures smaller than f5.6, just like all of Canon's
other non-1 series cameras (except the 3).
If you trick the system by using a 3rd party TC or
taping over certain lens contacts (no, I don't know
which ones) then the AF appears to work about the same
as Canon's other amateur EOS': bright enough light
and high enough contrast it works ok; low light or
low contrast and it hunts badly.
