DxO has tested the Sigma 85 Art. Nikon only (LOL).

I'm wondering why no 5dsr results? Do they afraid to give Canon a higher "score" because the lens probably resolves way too much?

Also not sure how do they calculate the CA. It's much more noticeable than the Otus 85 which is measured to have a higher level than the Sigma (3nm vs 2nm).

DxO testing does not account for the longitudinal CA being more pronounced with Sigma. Not a problem for studio shooters (the lens primary designation anyway), but could present an issue for outdoors. not too bad though.
