Tokina 17-35 f4

Hi all,

I have been browsing the forum for any reviews or remarks on the relatively new (2011) Tokina 17-35/f4, but with the exception of a couple of very short threads, found none. There are also only a couple of reviews out there. Has anyone tried this lens? How well does it perform? And how does it compare with other similar wide zooms, or with Tokina's 16-28/f2.8?  Any info would be greatly appreciated!
