An additional test at 21mm/F5.6, using what I think is the weakest corner (wide open) on my zoom at that focal length, and compared against my Nokton 21, also at 5.6. 100% corner crops from 42mp, minimal CR default sharpening.
By F5.6 btw, the zoom seems essentially flat field for practical purposes, and across the full zoom range. Note also the CA advantage over the Nokton even at F5.6.
