This is basically a bokeh test, and the 16-35/2.8 wins.

Let me guess - you focused in the center which is very deep into the scene, and expect the corners, lying on a focal plane much much closer to you to be in focus?

See note at the beginning:

(To the nitpickers out there--if you don't like the way I did the test, buy your own darn lenses!)

Good answer. Ironically, on another thread where i tested the corners of another UW lens, his harangues were that I had focused on the corners. Next thing he'll spring up is Field Curvature without ever determining whether the particular lens in question does in fact suffer from it. So dambed is you focus in the center, and damned if you focus on the corners.

The onus of the evidence is on the one making the claim, not on the one questioning the claim.
