Starring Campito the feral horse grazing at dusk*, this aperture series from f/1.4 to f/5.6 assesses across-the-frame and near-to-far sharpness, secondary color correction, and focus shift. The lighting was extremely blue, which is always difficult challenge for a lens, the blue/violet spectrum being the most difficult to correct for. It does appear to be a factor.
Includes images at up to full camera resolution from f/1.4 through f/5.6 with crops.
The about $1199 Sigma FE 85mm f/1.4 DG DN Art offers very high performance, but it has some behaviors worth knowing about for optimal results.
