Is there corner shading on the Sigma 120-400mm?

Corner shading isn’t an issue with the 120-400mm mounted on a subframe camera body; the worst-case scenario is noted when using the lens wide open (ƒ/4.5-5.6), and even then we note the corners only a quarter-stop darker than the center. At any other apertures, corner darkening is insignificant.
