Well, although I said any prime, I wasn't thinking of the 30 at the time (even though I own one). I don't think edge to edge it's going to be as good as the other primes, probably more on the order of the 8-16 in terms of sharpness...I'm surprised Kendall didn't mention it in his other replies but it is not the lens at fault - see his reply here for "proof" - http://forums.dpreview.com/forums/read.asp?forum=1027&message=38773039 . I hope you apologise for any slur on Sigma equipment as you and not the lens are obviously to blame ;-)
A revised 28mm prime would be great, and there appears to be talk of a re-designed 12-24 which might be really good.
