Hey Folks, I'm in the market to purchase a wide angle lens for my D90. I've been seeing nothing but ++ for the Tokina 11-16 and Ken Rockwell mentioning it's the best wide angle lens for DX systems... The 10.5 Nikkor fisheye has opened up my eyes to an even wider lens with fisheye capabilities. I'm torn between either lens. Any help is appreciated. Thanks!
