Not being an UWA guy, I'm not sure if my copy of this well-regarded zoom is up to par. The IQ does look much, much better than my Sigma 10-20 on APS-C, particularly on the longer end. On the 16 mm end however, the extreme lower corners are not as sharp as the rest of the frame (but then perhaps I'm expecting too much?).

I did shoot a detailed wall and the IQ at the wide end is similar to the one posted, hence I'm inclined to believe that DOF is not the culprit at the extreme corners.
Any comments will be appreciated.
Thanks,
Romy
