I think a bit of both! The normally very accurate D200 metering seems to be slightly off with this lens, especially at small apertures. the exif is recording the correct distance, and the 9 blade aperture is closing down OK, so it must be the unusual optical arrangement of the lens which also confuses the autofocus system at max aperture and minimum focus. The optical construction is discussed here
