Of course.
That's exactly what I was thinking: that the native optical focus shift might be being compensated for in firmware.
And it *could* work in manual focus mode in a fly-by-wire camera with a lot of af sensors: you focus manually, and it compensates as you take the picture if the lens is stopped down.
Of course to do it accurately without the knowing roughly where you are focussing would be hard
