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

That seemed odd. I use the autofocus, but I use it
carefully.
So, this evening I tested the focus on my K10D using

I'm concerned that correcting the back-focus with the
16-45 will make the 50-200 and 50/1.7 front-focus. Is
that a legitimate worry?
