Sigma 20mm 1.8?

I own the Sigma 20mm 1.8 and it tends to be soft in the corners in FX use, which has been reported by others. So I don't understand how to take the high marks in this report. The lens works well otherwise but certainly isn't a match for the Nikon 14-24mm set at 20mm which holds sharpness well edge to edge. The Sigma is better in DX mode where the edges remain sharp.
