Just FYI, you can see a full-resolution jpeg of the samples by clicking on: (点击此处查看大图) located directly below each image.Doesn't look very sharp in the corners (photo of the white house and the church). Or am I a pixel peeper now and does it look better than the 16-35 f/2.8 II?

This new lens seems pointless to me - it's even longer than the f/2.8II and weighs almost the same. The 17-40 is the hands down winner for travel and portability in general. If I'm going to lug a WA that big, then it better have a 2.8 aperture.
