noticed in another thread someone saying 18-50/2.8 will not work
with the 500's focus assist lamp. is this a common problem? i was
under the impression that the 500 super was the solution to sigma
lenses not working with the canon external focus assist lamps? this
doesn't hold with the 18-50/1.8?

It definitely doesn't work with the 580EX, don't know about Sigma flashes.
