Are you using sigma 30mm non art one. DPP is not showing outer active points with sigma 30mm. It only recognize center active point. Looks like Sigma doesn't know full AF communication interface. Will Sigma fix this under warranty.
Yes the lens is a Sigma 30mm f/1.4 non-art, about 3 years old, absolutely no issue with focus points on my 70D, images are razor sharp using any focus point.
