Yes, you're right. I just wasn't clear. I was talking about getting the 30mm with HSM in our mount.

I haven't heard of the DA* AF being inaccurate, I've just heard of it being numbingly slow. It seems that the SDM problems have diminished; however, if you're uncomfortable with it, it's something to factor in. The main issues I've heard of were on the 16-50. Those seem to have subsided. It's possible they started putting the new "DC" motor in it, that more than likely is a similar set-up, just perhaps some new configuration to mitigate failures.
HSM, on the other hand, seems to get rave reviews. I wish we got the 30mm in our mount. It'd be a fun pair (50/30) to quietly play with.
Do as you plan. Swap it out with another copy. See what happens. If it's another dud, see how you feel. If it's more discomfort and disappointment, then just throw in the towel and go with a different model. Best of luck.

I hate to say it this way, but Sigma just seems to be "like that". When they're great, they're great, when they're not......well, it's like this lens. Frustrating. There's many people that have gone through a few copies of the 30mm before getting a good one. With the good ones, though, the sky's the limit. From what I've read, the 50mm seems to be even better.

With the trouble you've gone through, and the diligence you've done, I'd just swap for a new one while you can. No sense in not taking advantage of that option.
