Hi,

I have been struggling with the same question. It looks like Tamron is sharper than Sigma but the reviews aren't quite consistent with this Sigma lens (some say it's soft at 70mm, some that it's very sharp, same with at 200mm). Sigmas might have AF problems with SLTs too. So I'm leaning towards the Tamron even with the significant price difference. I would be very interested in hearing more about actual users of either lens.
