Could you explain the result of sharpness for Sigma 85mm F1.4 EX DG HSM Nikon? When I have compared it to Nikon AF-S Nikkor 85mm f/1.4G, Nikon AF Nikkor 85mm f/1.4D IF and Samyang 85mm f/1.4 Aspherique IF, Sigma was given the lowest score of 12.

But after I have reviewed all measurements for sharpness that you published I can't find such large differences.

Sigma 85mm F1.4 EX DG HSM even got the same sharpness result as Tamron SP AF 17-50mm F/2.8 XR Di II LD Aspherical [IF] Nikon. I own both and the difference is immediately noticeable in favor of Sigma.

               d7100   d600   d3x
Nikon AF-S Nikkor 85mm f/1.4G      16   20   19
Nikon AF Nikkor 85mm f/1.4D IF      14   16   15
Samyang 85mm f/1.4 Aspherique IF Nikon   14   17   15   
Sigma 85mm F1.4 EX DG HSM Nikon      12?   18   16

I assume that there was a typo and that the result is 15...
