I quite enjoyed the Sigma 180mm f/2.8 when I reviewed it. I didn't do anything scientific, just tested it in use from a non-macro shooter's perspective. I was really impressed with the sharpness out of the camera without adjustments and the focusing accuracy left little to be desired.

The IS in the latest 100mm macro is supposed to cancel lateral vibrations, improving quality near close focus. Do any of the long lenses have similar reduction? I don't know what's inside Sigma's "OS".
I presume you're talking about the Canon 100L macro? I thought IS lenses always corrected for lateral vibration, but that the new thing about the 100L was that it also corrects for rotational vibration.
