Sigma has two 18-50f 2.8 macro lenses. The older one uses 67 mm filters, and is reviewed in photozone.
The new one uses 72mm filters. It is also a fixed f2.8. Both are f2.8, not variable f2.8-f4.5, but one model is older.
The only review in Canon mount that I have seen is on the Pop Photo website. They say it is great, but everything seems above average in Pop Photo world.
There is a review of the new one, but as Kenjis pointed out - it is a Nikon mount and has HSM focusing.

Actually its the one without HSM focusing, its the one thats Screwdrive..
For Nikon theres THREE variants, 67mm, 72mm Macro and 72mm Macro HSM..
Keep in mind the HSM version isnt really a big difference than the Canon one in this case because the HSM used in it is still a micromotor..
I for one am really hoping Sigma will break the trend and offer a lens in this class with a ring-type HSM motor and OS..A TRUE competetor to Canon's 17-55
