I just got the Tokina 11-16 f2.8 in the mail today, went out and did some shooting, and wow, this lens is freakin awesome. My photos are now sharp as a tack.

I drove over to Clarkseville this afternoon to redue a photo that was kinda blurry.
Heres the photo with my 12-24
Basically the same photo and lighting taken with the 11-16mm today. Notice how much more incredibly sharp it is. Im going to love this lens. Ill take some comparison shots later tonight with both lenses under the same conditions. I only wish I had this lens when I spent a bunch of money and drove out to eastern Arkansas.
Every review Ive read said this lens is the sharpest wide angle, even better than the Nikon or Canon equivalents and Id have to agree. Plus, its about half the price of those lenses. Distortion is also almost completely gone compared to my 12-24. Even at 11mm, it doesnt look distorted and its sharp, even to the corners its super sharp.
