Even the 5D II which claimed has been taking care of AF issue at different
color temp. has problem, it fail with my Tamron 70-300 when I was shooting
my son's U. Grad. Ceremony inside a hall. For day time shooting it was
perfect, similar problem happen with my 40D but it could be a lens and
camera matching issue.
