I have ha the same problems...I have had two chances to photograph ice hockey games from the box...and it is the toughest thing ive done....
my next alternative is the following:
Older OM style lens (50mm f1.
with an adapter for the e-510
i tried taking shots with manual focus and it does not seem to be dificult.
I will let you know what happens.....
