Which Sigma SA-mount lenses cover the Sigma sd Quattro H sensor without corner vignetting?

I’m looking for Sigma SA-mount lenses that work well on the Sigma sd Quattro H (APS-H) and give good corner-to-corner coverage. Since the sd Quattro H uses a larger sensor than APS-C, I’m especially wondering whether Sigma’s APS-C-only DC lenses—such as the 18-35mm f/1.8 Art and 50-100mm f/1.8 Art—can deliver sharp, usable corners on the larger APS-H sensor, or if only full-frame DG lenses reliably cover it.

Sigma's DG lenses, which project full-frame–sized image circles, won't vignette on the sd Quattro H. To my knowledge, nobody has compiled a list of every Sigma DC lens for the purpose of describing how much each lens will vignette; it's safe to assume that every DC lens will vignette on the sd H to some degree or another, simply because those lenses are designed to project an image circle sufficient for 1.5-crop APS-C sensors, not 1.3 APS-H.

Some example discussions or resources/images regarding DC lenses on the sd H:

For the sd Quattro H, the safe choice is Sigma DG lenses. DG lenses are designed for full-frame image circles, so they should cover the APS-H sensor without the vignetting issue you can expect from APS-C-only DC lenses.

There does not appear to be a definitive published list of DC SA-mount lenses ranked by how well they cover APS-H. The general rule is that DC lenses were designed for APS-C coverage, so on the larger sd Quattro H sensor they will vignette to some extent. Community examples with DC lenses show noticeable dark corners, and stopping down may reduce it but not necessarily make it acceptable.

So if your goal is reliable corner-to-corner performance on the sd Quattro H, look for DG lenses rather than DC lenses. For lenses like the 18-35mm f/1.8 Art and 50-100mm f/1.8 Art, assume they may not fully cover APS-H well unless you can test a specific copy yourself.
