Looking at the camera.cpp file I see that the default values for focal
blur is not what is said in the Documentation.
camera.cpp:
Make_Vector(New->Focal_Point, 0.0, 0.0, 1.0);
New->Variance = 1.0 / 10000.0;
Povray Documentation (6.4.3 Focal Blur):
"The default value is focal_point <0,0,0>"
"variance ... (the default is 1/128)."
I hope I didn't misunderstand anything but it looks like the actual
Focal_point is the camera's Location plus <0,0,1> (one unit to
z-direction) if the Focal_point is _not_ defined. If it _is_ defined,
then the vector represents the actual pointm not offset. Please double
check this. Variance seems to be really 1/10000 instead of 1/128.

I think you had better get in touch with the POV-Team, not this
newsgroup. I only translated the html version of the manual into a
printer-friendly pdf, and I did that by dragging-and-dropping the text a
chapter via the next.
Anyhow, I went through version 3.1 and found it reports exactly the same
he
text is the same. See Pov Manual version 3.1, chapter 4.4.6.

Umm, I don't quite follow you. I thought this group is about
"Discussions about the POV-Ray documentation" (quote from the
description of this group). I was really talking about the official
documentation, not the pdf - allthough the errors are probably there
too. I also though that this group is the way to get in contact with
people maintaining the docs (Ingo?).
But I'll naybe ask also in another group. Maybe the docs are correct but
there is a bug in sources ;)
