True enough. I'm not attached to the idea of more AF points, though I could probably make use of them on occasion, I use center-focus most of the time, but there's curvature of field and other factors that'll make me want to use other points.
For me, if I have to use automation at all, I'd prefer it to be as swift, sure, and precise as possible, but as the industry standards get faster and faster, we're talking about smaller actual intervals of time we're comparing.
A really precise screen useful for manual-focusing with fast lenses would do as well, even if the AF only had like *three* points. (It's still mostly a crutch to me, the AF, anyway) Though I think my real high-tech dream would be an eye-or-thought-controlled floating AF point. (I always wondered why that tech seemed to dead-end and never get picked up again, the early versions impressed me) I don't think in terms of points, I think, I want the focus point *there,* and AF is just an indirect way to make that happen.
Anyway, my K20d could be better: (if I ever get focusing-screen happiness then it'd be centerpoint-or-manual focus nearly all the time, anyway) but people do have different needs. This AF system with the + would be great, actually. There's points and then there's having another AF sensor to read them for any errors.
People 'compare' a lot when it comes to things like this, but I think the real question is, 'How many jobs can this system do?'
My jobs aren't heavily-demanding: where it gets tricky is old training (good) and aging eyes (Not always so good) It's not so much speed as responsiveness, sometimes. One thing machines may never do is really read human body language and make all the subconscious corrections that you would in MF when interacting with people: the best it can do is shrink the time it takes to catch up. Advantage, sometimes, precision, if you can tell it what to aim for fast enough.
For extreme sports and birding and all, though, there's someplace where lots of points probably would help. I imagine a smart AF system could pick out the bird in the sky from anywhere in frame.
Rambling.
