It's just weird that the lens won't focus at all unless it's borderline focused on a subject.

I need to try a different piece/specimen (what's the word in english damnit?) to find out whether this is normal or not.

Maybe you have bas sample, mine worked great even on Canon 350d back in 2005 if I remember right.
