While looking at the score card we generally roll eyes to the sharpness score of any lens and after that we look at for Distortion, vignetting..etc.
While looking at the score card of Sigma you can see that lens is even more sharper then Ultra Expensive Carl Zeiss Otus. But, At the same time we can’t ignore that Tamron SP 85mm F1.8 Sharpness score is also same as of Sigma 85mm F1.4, but it goes down in table due to bit more distortion and Chr. aberration.
