One other combo you might want to look at is the 100-300 f/4 + 1.4x tc That gets you to 420mm at 5.6 and the 100-300 is very highly regarded.. The only downside of that is that the K10D does not seem to be aware that a TC is in use and hence the SR system's performance is not as good as it should be coz it is correcting for a shorter focal length.
