Not sure what your point was, but I can guess. Anyway, here we go.
If you were shooting sports, it would be another thing. For instance, I did a basketball tournament this December. There were 10 players to a team, and I was selling the pictures to the parents. I tried to get 20 pictures per player, because that is what parents buy. So, you figure... I have to take 200 KEEPER images in 32 minutes. That's 200 where they are doing something cool, jumping high, juking around an opponent, etc. Why do I need 20 pics per player? Because that's what parents buy. When parents buy photos, they don't buy one or two like the newspaper does...they go all out and buy everything I have. My main problem is not having ENOUGH. Basketball is too unpredictable to require that many shots with MF in such a little amount of time. Any time I see a moment, i rely on mashing the button and a sharp image coming out, without having to spend the time and risk with MF. That's just me, because I am not good enough to use MF for all these shots, let alone MF with such a shallow DOF as f/1.8 provides. With a baby rocking back and forth, you bet you can guess where he's gonna go next.
What I'm saying is that some of your points aren't valid, and don't apply to everyone. What I'm also saying is that you are closed-minded to the situation and you need to understand that the D40 does have this limitation, and this limitation WILL limit SOME people (myself included).
So, is it fair to say that MF on a D40 and a non-AF-S WILL hinder SOME people?
Is it fair to say that the D40 is a BEGINNER's camera, and most BEGINNERS don't know the type of photography they'll get into?
This isn't about the D40 anymore. Just be careful how you're coming across, because you sound closed-minded - that "Nobody NEEDS AF". I am one who DOES need AF at times (sporting events), and whether a sissy or not, that's me. I'm sure more people are in the same boat.
