I suppose I should also point out that Nikon fires a pre flash  prior to
the actual flash exposure so it can meter the reflected light of the
flash from the subject. The metering is also tied to the active AF
sensor. In my experience with slide film, it deals very well with an off
center subject that is against a very dark background.

As I said before Nikon's flash metering is very good, except for one
drawback - pre-flash metering doesn't work when using bounce and wireless
flash - it switches to simple TTL in these situations.

On Pentax P-TTL, pre-flash metering works allways when using bounce or wireless flash !
