I don't know exactly how much mine is, but it's somewhere close to 3
inches. Either way, the camera usually obstructs enough of the light to
prevent the autofocus from kicking in well before the camera gets too close
to focus.

Alright, now I'm envious. I have sometimes wished I had a third hand
to help juggle things because there wasn't enough light for the autofocus to
read the distance. I think this was the worst ever:

In order to get this shot, I had to have the right can-light and the
top-light on to get the camera to focus, as every other light in the room
had to be off. Then, while holding the shutter button half-way down to keep
the focus, I had to turn off the top-light and then hold a red gel filter in
front of the right can-light before snapping the shot. And it took more
than one try to get through all of that without having my finger slip off
the shutter button long enough to lose the focus. Ironically, I probably
didn't really need to have a clear focus, given the look I was going for,
but I hate taking blurry photos.

Okay, now you're getting way beyond what most people will ever have the
capability of doing. Even good general use digital cameras don't typically
get that complicated. That's largely left to cameras designed for real
photobugs, and rightly so. The average consumer just wants to be able to
shoot family snapshots and general scenic shots during holidays and
vacations, and they don't need many bells and whistles to do that.
