There are 2 other boards involved if converting an old camera to CE, 
that can't be done.  These boards could be used if camera is already CE 
version. Then board must be programmed.
Tamron's going very well.  I've been trained and certified on 17-50mm 
VC, 200-500mm, 60mm Macro, 70-200mm f2.8, 70-300mm VC, and the new 
24-70mm f2.8 VC.
