I'm a bit baffled by some of the comments on this topic. I have the AF-assist
turned off (CF 7 set to "1"), and in the "Creative Zone" I can't get a pre-flash
under any circumstances, at least not with the built-in flash; with the 550EX it
doesn't matter anyway since the 550 uses its red lamp for AF assist. Since in
the "CZ" the built-in flash doesn't pop up automatically, I don't really see the
AF assist as being a big issue.
In a darkened hallway where the recommended exposure was 1.5 sec @ f/4.5, or
about EV 4, I was able to AF on objects in a dark corner without too much
difficulty. Ok, so it's not night and it's not EV 0, and the focusing wasn't as
instantaneous as it would be in better light, but it was faster than I could
have done it manually. There was some hunting perhaps, but there's hunting and
then there's hunting, if you get my drift. This was with the slowest lens I own,
a 28-105/3.5~4.5, at 105 mm.
In other words, it seems odd to me that an EOS 30/Elan 7 with a Canon lens
mounted would have any difficulty focusing in a store with average lighting,
even with the AF assist turned off. As for not being able to completely disable
AF assist when in the "Basic Zone," well, it is the "Basic Zone," after all.
