I will check again among all the pics I took for testing but if I recall I was getting good results shooting at aounrd 1km distance at 400mm with 1.4x only if fstop was 7.1 or even better at f8. And was getting similar good results at f5.6 if I was backing the zoom ring in the 350-360 range. But it's true that 400mm at f5.6 is not that great with 1.4x. It seems it was more obvious in long range than short range like you mentioned.
