OTOH you could look at the F100 instead of the F5.
It's not a question of need, but yet another advantage of the F5. No one *needs* HDTV either.

F5s are more than F4s, but the autofocus improvement alone makes the increment worthwhile to me.

The F100 is a great camera (I've owned one for a few years) but so far I like the F5 better. The F100 is smaller which is occasionally good. Since I have both, it's not an issue for me.
