Kurt Munger (Click here) posted a full review of the Tokina 11-16mm F/2.8 lens: “The Tokina performs superbly at the shorter focal lengths, with sharp centers that nearly match the mid-sections and corners when stopped down. It has some of the sharpest corners of any super wide zoom I’ve ever tested, and that’s saying something!“.
