    When I set the ISO upper limit to 6400 it flashes in the display when used. This is not the case if I set it to 5000. Anyone knows why?

    Presumably you can't close the lens further to allow a proper exposure??

    When I manually chose ISO 6400 and above, it says "Extension". So there is some technical term for ISO above 5000?

    When you choose 6400, the camera actually uses 5000, but boosts the exposure via internal software. You can get the much the same effect by underexposing at ISO5000 and correcting in your favourite raw image editor.
