Trap focus only works with manual focus lenses and only when the AF/
MF switch is on AF. Because it only works with manual focus lenses,
only the center focus sensor is active regardless of which focusing
mode you've got the camera set to.
Shel, you probably have the AF/MF switch set to MF.

You shouldn't have to set a menu item. And if it's set on
autofocus, it shouldn't fire until something is in focus. You would
want to use selective focus. If it's on multipoint, it will find
something in focus other than the subject.

OK, that's what I thought, but the camera fires even when there's
nothing
in focus. Is there a menu item that has to be set?

I seem to have forgotten how trap focus works on the istDS.
Can someone refresh my memory?
With a manual focus lens, set a focus distance and flip the AF/MF
switch to AF. Hold the shutter release button fully depressed. When
the AF sensors pick up a subject in focus, the focus indication
light
will turn green and the shutter will trip.
