Nice suggestion Chuck!  I wish my RBT S1 had this option!
Sometimes I clearly see that the focus is better in front
of the subject (where it is wasted) than behind (where it
is really needed).

What I then do is this:  I frame the subject and half press
the button (to lock the focus) and then I move one step back. 

Oops!  I just figured out I am all screwed up!  I should
be moving one step forward.  Wait.... which way should
I move after I have locked the focus?

Seems like I should be moving closer.  This way the camera
will be focused slightly behind the subject to give me
better depth of field.

This also follows the old advice:  After you compose your
picture and you are ready to shoot, take one step forward.
This advice aims in creating tighter compositions.  At
the same time it will create a better depth of field
for my stereo picture.  Two birds with one stone!!!!
