I admit it wouldn't be the first time for me having a rather obscure way of
seeing and understanding common things, but personally I've just always found it
important for the scene to fine-tune look_at and focal_point independently to
get the camera angle as desired and furthermore to have the blur in the correct
point. My own recommendation would thus be that it certainly depends on what you
are having in the scene and what you want to emphasize. :)

Ah, of course, forgot about that one completely. I should sleep more. Or drink
more tea. %-)
