Happened across this thread, figured I would chime in..
if your using a moderate grade point shoot or a DSLR and shooting close up at the face, dont stop down lower than 3.5 or so, because then you can run into issues with the nose being out of focus, when they eyes are in focus or vice versa.. well unless you have a persian I guess. but also dont go too high or you will get too much background and a soft front.
