For a long time i've owned the Sigma 20 and 28mm 1:1.8 EX DG Macro lenses i've used mostly the 20mm a lens of wich some people complain it to be "soft" though i can tell you it is plenty sharp for me especially if stopped down only a little bit from 1:1.8 to 1:2.
Now when launched there was a third lens in this series the 24 1:1.8 EX DG Macro wich i never got around buying. But last week i saw one for a price i couldn't resist and bought the missing link in my macro wideangle range. On Nikon the af of these lenses is screw drive but because of the short focus throw they still focus very fast.
Maybe not for everyday use but still fun to have.
Here's the same shot taken with all three of them wide open, this shows, with the same magnification, the difference in perspective.
And here they are next to each other:
This is an example i've made to show the good front to back separation wich can be achieved with these lenses wide open (the 28mm on full frame was used for this shot)
Here's another one, this time with the 20mm on DX (wich makes it a 30mm)
