<< Can an AF sensor focus on something as small as an eye? It seems that,
from what I understand you to be saying, it may not be possible to get that
precise, and that MF may well be a better, more accurate, method of focusing
when making typical portraits, especially if one were to be using wider
apertures.
Is that a realistic conclusion? >>
Shel, when perusing the supermarket tabloids, you'll notice that almost
without exception, regardless of time of day the photo is: 1)shot autofocus
TTL 2) dark, except for the principle(s), who are always properly lit 3) in
full face shots, the eyes are ~always*~ in focus. 4) the subjects many times
are on the move, meaning autofocusing is the only way to go (for candid
shots).
*Because the camera is more than likely loaded with ISO 8000 film which
indexes at f/9.5 or f/11 under a TTL flash, nearly guaranteeing sharp focus!
But for portraiture, you ought to use manual focus, trying to set the ~exact~
plane of focus ~just *behind* the eyes~, never in front.
*Focusing just behind the eyes gives them depth.
*Bad news: if you are shooting wide open and have a fidgety subject who rocks
to and fro (in the direction of, and away from) the camera, manual focusing
can be very imprecise, (as you probably already know).
