Focus shift; basically closing the aperture changes the point of focus.
I've never bothered to look up why this is the case; though I'm sure someone with a bit of physics in their background could explain it.
What I do not understand is why cameras are not programmed to compensate.

Markus, thanks for the great review!
Sorry to ask for this, but some times I am confused by "focus shift". Is it possible to add the definition of it in PZ glossary page where you explain the basic terms about photography? Thanks in advance.
