I'm beginning to wonder about the reviews of the Canon 28mm 1.8 and the Sigma 30mm 1.4 (DC, so not for FF) and I'm (still) trying to decide between the two.

The tone of the reviews here seems to suggest the Sigma performs better. But I've read some truly horrible reviews of it.

Would love a definitive, "this lens is better than that" answer, but I don't think I'm going to get one.
