Re: 12-24, 550EX and 10D Work Perfectly (nt)

my sigma 12-24 DOES NOT work with Metz and Sigma500 DG super
Both Flash AF beam cause the lens to focus past infinity

For those who want to test this, go into a dark area
then push the focus ring to closeup and aim at something 6ft away

dont be an idiot and test AF assist beam in a bright room :))
