From: Larry Colen
I'm going through my dance portraits from Saturday night, and I'm
finding a lot where the K20 missed focus. I was mostly shooting with
the 16-50 on the K20, at about f/6.3. I could have cranked the strobe
up higher, but I didn't want my home depot backdrop to also be in
perfect focus. There was one batch where the back of the leader's
sweater was in focus, but the dancers faces were just slightly soft.
I don't know if this was mis focused on the sweater, or just a blown
focus where DoF still caught the sweater, because there are others
where everything is sharp.
I've got a bunch more that are simply blown focus. It could simply be
pilot error because when people are dancing I lock focus, and hit the
focus lock so that the shutter will activate when I press it. I'm
afraid that I don't trust the responsiveness of the autofocus, and
may be screwing myself up there. I expect that the problem is a team
effort between the camera and myself, exacerbated by my not trusting
because the focus is slow and perhaps a bit unreliable.
Or, as a wise man once said, "Aaarrgggh".
Something like this I'd probably go with what I call a "zone focus",
setting it up so the near and far limits of the D.O.F. bracket the
dancers and not even try focusing on the individual couples.
That used to be pretty easy to do with manual focus lenses that had
D.O.F. scales.
