I had the Sigma 28-70EX f2.8 DF, the one with the distance window but I sold it off as the flare was so bad. This new Sigma (MACRO) is faster, quieter and has better flare control.
On the other hand the sharpeness, although in pure terms sharper than the canon, is very ugly. It seems that Sigma have tried to make this lens as sharp as possible through very high contrast. It looks like excessive USM does in PS, but all in all the sharpness does not look real or pleasing. It doesn't resolve as well as my 17-40L on the 10D either. I sent it back to the store after about 1000 frames over two jobs and am buying a 24-70L to go with my new 1Ds.
A lens is not just about the sharpness, the 'look' of the sharpness is also a factor and here Sigma falls on it's face.
