From the experience of users in Japan, Sigma has an excellent record in admitting poor product performance and prompt replacement within the warranty period. If I was disappointed with the performance of a lens that others had found "outstanding" I would be back at the ship demanding a quality check and either adjustment or replacement. This might be harder for purchasers overseas... How would you pay for the to-ing and fro-ing of products that proved to be within spec?
That said, they do appear to have a quality control problem. My own 8mm f/3.5 Sigma is on a par with the excellent 10.5mm Nikon fisheye.
