Just did a tripod/target test with a bunch of lenses to see what the difference on them is on my 5DII. Included a 28/1.8 and 35/2
Taped two targets up on the wall, one dead center and one right on a corner of the frame. Took shots with each, moving the tripod to get the corner target in the right place.
35/2 was ok in the corners wide open, sharpened up fairly quickly.
28/1.8 was sharper int he corners at 1.8 than the 35 was at f/2, and got incredibly sharp at 2.8 all the way across.
maybe I have a good 28/1.8 (or mediaocre 35/2). But between the two, I've always preferred the results from the 28/1.8
