The only other thing with the Sigma is that it doesn't focus as quickly as lenses with USM/HSM (SSM or whatever Sony class it as) but it is still fine for general use.
What I found interesting was a comment from a Sony A700 owner I saw a week or two ago another forum.

This user has both a Sigma 70-200mm f/2.8 EX DG lens (without HSM) and a Sony 70-200mm f/2.8 SSM (Sony's equivalent Supersonic Motor Feature). He said he thought the Sigma actually locked focus faster (despte the lack of HSM) on his A700 (probably in thanks to the new beefed up focus motor).

But, he said the Sigma was not as accurate with a small amount of backfocus frequently (he thinks he may have gotten a lemon, since others in the same thread said theirs worked fine).

But, Sigma will be including HSM on some of their newer lenses in Sony/Minolta mount now (including the newest Macro II version of their70-200mm f/2.8 ). It would be interesting to get some Sony owners impressions of the difference HSM makes on a newer Sony body, if someone out there happens to have access to both Sigma 70-200mm lens types (with and without HSM).

What does this mean: But, he said the Sigma was not as accurate with a small amount of backfocus frequently (he thinks he may have gotten a lemon, since others in the same thread said theirs worked fine).

Back focus problem??
