After a year with the K20 I used the select point for the first time. It was useful for when I wanted to hand the camera to somebody else and have them take the picture. I didn't want to have to explain how to use the lock focus and recompose feature especially since none Pentaxians tend to press the shutter too hard and thereby actuate the shutter rather than just focus. Canon users are bad for this.
if I answer truthfully, I focus by turning the focus collar, or, I press the shutter half way and let the camera do it?
Both seem to work.
As for focus and recompose, I have tried this and find that it is never as sharp as using the selectable focus points.. I think re-composing when you are fairly close in causes too much movement and you upset subject distance.
I always center point and recompose now. My first DSLR, the K2000 never allowed me to select AF points and I was so used to not using them, I tend to not use them on my K-7 also.
typically i've used the center focus point and recomposed. But that can alter your plane of focus so I've been trying to get used to selecting the autofocus point. But then maybe your focus isn't as accurate??
What I do know is...at both a wedding and a hockey game just this past weekend, I tried using continuous focus and failed miserably with the DA* 50-135. It couldn't even keep up with bridesmaids walking slowly towards me. Is it something I did wrong? Or just the slow speed of the K10D + DA*? I don't know...but I'm not happy about it. I was only the third shooter so not that big a deal, but man, it really bums me out that those pics aren't sharp.
I usually center focus then recompose, but I am returning to manual focus more and more. I am finding that the auto focus is not always reliable, and is slow in low light. Using manual focus also gives me reason to use my Super Tak 50 more often!
I use the centre point and then recompose. I have my camera set to single not continuous focus. Occasionally I use the points, however, that is probably only less than 5% of the time.
I usually use centerpoint-recompose but I'll shoot manual as needed. I've also been known to pre-focus and wait for the subject to pass into the frame.
Center point and re-frame can be very dangerous. If I were to do so all of my images would be focused on the wrong unintended point. It only works if perfectly perpendicular to the subject and at a considerable distance.

Well, it only works *perfectly* in those cases. But really, the amount by which the focus is off in practice is usually less than the DOF, *unless* you are shooting a scene with an extremely shallow DOF (as your example obviously is). It's an issue mostly at apertures of f/2 and below, and especially at very close focus distances. For me personally, that's an extremely rare combination. But for some, it will be more common, indeed.
