I'll be guessing a a large aperture portrait lens. And the reason the rating is missing ie because the way PZ does the MTF testing (with a simple sharpening step) the 5DS-R results looked rather dismal in corners, so a rating was a bit difficult to give without getting a feel for the high res. sensor with the test conditions.
In my opinion, don't let low-ish corner results from 5DS-R PZ/OL deter you from a specific lens type.
