Have to disagree.
Just as an extreme experiment, I just switched off all lights and took a
photo in total darkness (AV, with flash up). It still focused.
The reason I asked what lens is because a small aperture lens will not be
as
effective in low light.
The reason I asked how far was because maybe he was too far away from the
subject for the flash to effectively illuminate the subject for AF assist.
I agree that another option is to use IR, such as a Speedlight or an
SE-E2.

Why? It happens all the time in low light situations. That's why the
lenses have a switch to shut off the AF. Tokina even makes lenses
that you pull the focus ring towards you and overide the AF (which is
nice). If you haven't experienced the joy of AF that can't find a
focus point, you haven't used your camera enough.
Sometimes you need to throw on a flash just for the IR focusing.
