Re: Autofocus issue with Sigma 10-20mm? Help!

Ironically, I noticed not too long ago that my wide angle Tokina 12-28 focuses more perfectly with PDAF.  I wonder if any of this is related to 3rd party lenses just not always meshing perfectly with the body.  FWIW my tokina doesn't get to infinity focus fast enough in CDAF.
