What are the alternatives to the sigma 105mm f 2 8 dg dn macro art?

I don't have a list of other macro lenses to compare against the Sigma 105mm f/2.8 DG DN Macro Art, so I can't name true alternatives from here. What I can tell you is that it's a full-frame lens for Sony E and L-Mount, and on APS-C it frames like about 158mm.

The only other Sigma lens I have details for is the Sigma 28-105mm f/2.8 DG DN Art. It's a zoom, so it's a different tool for everyday shooting rather than a close-up substitute.

If you're deciding what to buy, start with the lenses guide to see how a macro lens fits into a kit, and check the sensor sizes page for how crop cameras change the framing and depth of field.
