This was available on my Nikon F100 as a custom function.

To the best of my knowledge, trap focus is strictly a digital camera trick. It
is a custom function (at least in the Nikons) in which the shutter is triggered
when something moves into a preset focus range. (hence the 'trap' term).
I used pre-focus a lot in sports photography back in the sixties and seventies,
long before autofocus. You can do the same but, of course, there's no
auto-magic about it.

I am looking for details on Trap Focus. Sounds like a neat idea but I can not
seem to find complete plan.
Google has lots of raves but each posting lacks complete details/options
Auto-focus lens vs manual focus.
Also digital vs analog???
I work with film so digital would be my second choice if this is not possible
with film.
