There's definitely QC issues, and the focusing differences between
the 350d and 30D/40D.

I agree with the point made about focusing differences between the 350D and 40D. My Sigma 30mm 1.4 consistently backfocused on my 350D, even after I sent it for calibration. That was very frustrating.

But when I got my 40D, I was very happy to discover that the focus was very accurate with the 40D.. no more backfocus. It is now perhaps my favourite lens. I'm finding myself liking it even more than the excellent Canon 17-55mm 2.8 IS, when I don't need the flexibility of the zoom.
