Now this is very interesting. I've been taking pictures of very small
birds recently and many of them
seem to be slightly out of focus. Once in a while there's a good one. In
my case too the in-focus plane
is always a bit behind the subject. The pictures have all been taken
wide open (f4.0) at 1/1000s.
I'll have to set up a test chart and see what's going on. Auto focus is
impossible since the birds
move around a lot and there is a very busy background. The lens (Sigma
70-300 Apo Macro) hunts like
crazy when I try auto focus. The same problem seems to occur with the
Sigma 400/5.6 APO MF lens.

Thanks for your comments. Since I'm not alone with this problem I
think I need to call Pentax service :(
This is the second "common" istD problem I encountered, a dead flash
circuit board was the first one: Are there any more common problems I
could check or get serviced?

I have noticed that many of my istD shots in manual focus are slightly
out of focus. The area in focus is "always" in the background of the
spot I focused on.
Now I'm wondering if I need to blame my eyes, the +/- slider of the
eyepiece, the mounting of the focusing screen, maybe the ccd
alignment???
