I took another careful look at "Loving Chimps", posted
earlier this week, and indeed it is back-focused. 
Several of my shots of the stone circle show the same
thing.

That seemed odd.  I use the autofocus, but I use it
carefully.

So, this evening I tested the focus on my K10D using
an off-camera flash, a detailed target at a distance
of about 1.5m, and three lenses (FA 50/1.7, DA 16-45,
DA 50-200).  The ambient light was from incandescents
and compact fluorescents.

Result:  The FA 50 was spot-on, the DA 50-200 was
slightly back-focused, and the DA 16-45 was
significantly back-focused (by about 20 cm at the 1.5m
distance).

Obviously any global adjustment that fixes the 16-45
focus will throw the other two off.  

Any similar experiences?

Apart from waiting to see if the individual lens focus
profiles in the K20D make it into a K10D firmware
update, does anyone have any suggestions?
