Doesn't make sense. The sensor in question is the contrast comparator AF sensor, which hasn't changed from the K10D far as I can tell. Ultra-ultra short focal lengths like this are always the most difficult for AF systems (and the human eye!) to manage critical focus with. But the K20D should work the same as the K10D in this regard ... the resolution of the capture sensor is irrelevant.
