A solution (I just thought of) would be to parent both a flat rectangle and
the camera to a null, then move the rectangle on the Z-axis to coincide with
wherever you want to focus. Your focal length is then read in the little
numeric Position box. Instant feedback!

Previously, I was using the Maximum Fog Radius sphere to determine focal
length. I set everything else in the Fog panel to zero, and made sure that
Show Fog Radius was selected in Options. Of course, this messed up any
actual fog settings I really wanted, but I could always restore those later.

I also thought about parenting both a light and the camera to a null, and
using the light's falloff sphere to get focal distance. But since falloff
only works as a percentage and not actual meters, it wouldn't be a good
approach.
