70-200 2.8 FF problem fixed!

I've been meaning to do this for a while, but finally got to it a while ago. My Sigma 70-200 2.8 has had a slight Front focusing problem which I addressed today. Using the debug menu key commands posted on here a while, I fixed the problem. -80uM in the focus adjustment menu and my 70-200 now kills. 2.8 is now supperrr sharp. So incredible. All my other lenses work fine if not better now as well.

It's only available if you have older firmware. v1.1 if I'm not mistaken.
