Weird test of Sigma 30mm ?

I don't believe to this test!
The new Art version of Sigma has absolutely the same optical design as the old version. The old version was tested by Dxomark and got 12-Mpix of sharpness where is the new version by Dxomark gets only 10-Mpix of sharpness. I suppose that there is a mistake or the copy of the new lens which was tested by Dxomark was defective.

The old version test : http://www.dxomark.com/Lenses/Sigma/Sigma-30mm-F28-EX-DN-Sony-E

Hello,

Thanks for your feedback, here is the comparison:
http://www.dxomark.com/Lenses/Compare/Side-by-side/Sigma-30mm-F28-EX-DN-Sony-E-on-Sony-NEX-7-versus-Sigma-30mm-F28-DN-A-Sony-E-on-Sony-NEX-7___828_736_1102_0
The 2 lenses are very close, a slight difference is noticed on sharpness measurement: the new version is slightly less sharp in the corner.
Results are very close, and should not impact the final image quality.

Best regards,

The DxOMark team
